There's more but these are the ones I need the most help with :/

"***" next to an answer means this is the answer I think it is
if a "?" is placed next to the question number it means I don't have any idea what the answer is even when trying to solve it.

my question to you is: Did you check your answers to see that they work?

#1 ok
#2 Ever hear of writing fractions for real? Why write "over"?
x/4 - 5 = -8
x/4 = -3
x = -12

#3 ok. What made #2 so hard?

#4
2(2-2x) =-3x
4 - 4x = -3x
4 = x

#5 ok

The ones you solved, you got right. Not sure what's bothering you on similar problems. Hang in there; it looks good so far.

2. x over 4 - 5=-8

x/4 -5=-8
x/4=-8+5=-3
x=-3(4)=...

2(2-2x) =-3x
4-4x=-3x
-4x+3x=-4
-x=-4 so x= ....

2. x=-12

4. x = 4
Thank you so much sir I understand what I need to do to now :)

1. -9x - 5 = -95

To solve this equation, we will isolate the variable x. Let's start by getting rid of the -5 on the left side.

-9x - 5 + 5 = -95 + 5

-9x = -90

Now, divide both sides by -9 to solve for x.

(-9x)/(-9) = (-90)/(-9)

x = 10

Therefore, the answer is C. 10.

2. x/4 - 5 = -8

To solve this equation, let's start by getting rid of the -5 on the left side.

x/4 - 5 + 5 = -8 + 5

x/4 = -3

Now, multiply both sides by 4 to solve for x.

(4)(x/4) = (-3)(4)

x = -12

Therefore, the answer is B. -12.

3. x/4 + 10 = 14

To solve this equation, let's start by getting rid of the 10 on the left side.

x/4 + 10 - 10 = 14 - 10

x/4 = 4

Now, multiply both sides by 4 to solve for x.

(4)(x/4) = (4)(4)

x = 16

Therefore, the answer is C. 16.

4. 2(2-2x) = -3x

First, let's simplify the expression inside the parentheses.

2 - 4x = -3x

Now, let's move all the terms containing x to one side.

2 + 3x = 4x

Subtract 3x from both sides.

2 = 4x - 3x

2 = x

Therefore, the answer is D. 0.

5. 2.9n + 1.7 = 3.5 + 2.3n

Let's start by grouping the like terms together.

2.9n - 2.3n = 3.5 - 1.7

0.6n = 1.8

Now, divide both sides by 0.6 to solve for n.

(0.6n)/(0.6) = (1.8)/(0.6)

n = 3

Therefore, the answer is A. 3.

Sure, let's solve these equations step by step:

1. -9x - 5 = -95

To solve for x, we can begin by isolating the variable by performing inverse operations. In this case, our first step is to get rid of the -5 term. We can do this by adding 5 to both sides of the equation:

-9x - 5 + 5 = -95 + 5
-9x = -90

Next, to isolate x, we divide both sides by -9:

(-9x) / -9 = (-90) / -9
x = 10

So the solution to the equation is x = 10. Therefore, the correct answer is C.

2. x/4 - 5 = -8

Similar to the previous equation, we need to isolate x. To do this, our first step is to get rid of the -5 term by adding 5 to both sides:

x/4 - 5 + 5 = -8 + 5
x/4 = -3

Next, we want to remove the division by 4, so we multiply both sides by 4:

4 * (x/4) = -3 * 4
x = -12

Therefore, the solution to the equation is x = -12. So the correct answer is B.

3. x/4 + 10 = 14

Again, let's start by isolating the variable. We'll begin by subtracting 10 from both sides of the equation:

x/4 + 10 - 10 = 14 - 10
x/4 = 4

To remove the division by 4, we'll multiply both sides by 4:

4 * (x/4) = 4 * 4
x = 16

Hence, the solution to the equation is x = 16. Thus, the correct answer is C.

4. 2(2-2x) = -3x

To solve this equation, we can first simplify the expression on the left side by multiplying:

2(2-2x) = 4 - 4x

Now let's distribute the 2 to both terms inside the parenthesis:

4 - 4x = -3x

Next, we want to isolate x. We'll start by moving all the terms involving x to one side:

-4x + 3x = 4

Combining like terms:

-x = 4

To solve for x, we'll multiply both sides by -1 to change the sign:

(-1)(-x) = (-1)(4)
x = -4

Therefore, the solution to the equation is x = -4. So the correct answer is A.

5. 2.9n + 1.7 = 3.5 + 2.3n

To solve this equation, our goal is to isolate n. We'll start by combining the constant terms on both sides:

2.9n - 2.3n = 3.5 - 1.7

Performing the calculation:

0.6n = 1.8

Next, we want to solve for n by dividing both sides by 0.6:

(0.6n) / 0.6 = (1.8) / 0.6
n = 3

Thus, the solution to the equation is n = 3. Hence, the correct answer is A.

I hope this helps! Let me know if you have any further questions.
