20=5−38x(1 point)
To solve for x, we need to isolate it on one side of the equation.
20 = 5 - 38x
Let's start by getting x on its own:
38x = 5 - 20
Combine like terms:
38x = - 15
Divide both sides of the equation by 38:
x = -15/38
So the solution for x is x = -15/38.
20=5−3/8x(1 point)
To solve for x, we need to isolate it on one side of the equation.
20 = 5 - (3/8)x
Let's start by getting rid of the fraction by multiplying everything by 8:
8 * 20 = 8 * 5 - (8 * 3/8)x
160 = 40 - 3x
Next, let's isolate the term with x by subtracting 40 from both sides:
160 - 40 = -3x
120 = -3x
Finally, divide both sides of the equation by -3:
x = 120 / -3
x = -40
So the solution for x is x = -40.
7(4x−15)=63
To solve for x, we need to isolate it on one side of the equation.
7(4x - 15) = 63
First, distribute the 7 to both terms inside the parentheses:
28x - 105 = 63
Now, let's isolate the term with x by adding 105 to both sides:
28x = 63 + 105
28x = 168
Finally, divide both sides of the equation by 28:
x = 168 / 28
x = 6
So the solution for x is x = 6.
−2(3x−15)−25=35.(1 point
To solve for x, we need to isolate it on one side of the equation.
-2(3x - 15) - 25 = 35
First, distribute the -2 to both terms inside the parentheses:
-6x + 30 - 25 = 35
Combine like terms:
-6x + 5 = 35
Now, let's isolate the term with x by subtracting 5 from both sides of the equation:
-6x + 5 - 5 = 35 - 5
-6x = 30
Next, divide both sides of the equation by -6:
x = 30 / -6
x = -5
So the solution for x is x = -5.
