The equation that is false is 1.3x + 2 = 8.

Answer 2

[AI-generated answer — Step-by-Step Bot]

To determine which equation is false, we can solve both equations and see if they hold true.

Let's solve the first equation, 1.3x + 2 = 8:

1.3x + 2 = 8
Subtracting 2 from both sides:
1.3x = 6
Dividing both sides by 1.3:
x ≈ 4.615

Now let's solve the second equation, 22x - 5 = 10:

22x - 5 = 10
Adding 5 to both sides:
22x = 15
Dividing both sides by 22:
x ≈ 0.682

Comparing the solutions, we can see that x ≈ 4.615 is not equal to x ≈ 0.682. Therefore, the equation 1.3x + 2 = 8 is false.

Hence, the false equation is 1.3x + 2 = 8.

To determine which equation is false, we need to solve both equations and see if the solutions make them true or false.

Let's start by solving the first equation, 1.3x + 2 = 8:

1.3x = 8 - 2 (subtract 2 from both sides)
1.3x = 6 (simplify)

Next, divide both sides of the equation by 1.3 to isolate x:

x = 6 / 1.3

Using a calculator, we find that x ≈ 4.615.

Now, let's solve the second equation, 22x - 5 = 10:

22x = 10 + 5 (add 5 to both sides)
22x = 15 (simplify)

Again, divide both sides of the equation by 22 to isolate x:

x = 15 / 22

Using a calculator, we find that x ≈ 0.682.

Now, let's check if these solutions make the equations true or false.

For the first equation, substitute x = 4.615:

1.3(4.615) + 2 = 8

This simplifies to:

5.999 + 2 = 8

Which further simplifies to:

7.999 = 8

Since 7.999 is very close to 8, we can consider this equation true.

Now, for the second equation, substitute x = 0.682:

22(0.682) - 5 = 10

This simplifies to:

14.964 - 5 = 10

Which further simplifies to:

9.964 = 10

Since 9.964 is not equal to 10, we can consider this equation false.

Therefore, the second equation 22x - 5 = 10 is false.
