Which of the following equations has a solution of −8 ?(1 point)

Question

x − 10 = 2

x − 8 = 0

x − 4 = −12

x + 3 = −11

Answer 1

To find out which equation has a solution of −8, we can substitute x with −8 in each equation and see if the equation holds true.

1) x − 10 = 2
If x = −8, then −8 − 10 ≠ 2 (which is −18 ≠ 2). So, this equation does not have a solution of −8.

2) x − 8 = 0
If x = −8, then −8 − 8 = 0 (which is −16 = 0). So, this equation does not have a solution of −8.

3) x − 4 = −12
If x = −8, then −8 − 4 = −12 (which is −12 = −12). This equation holds true, therefore, it has a solution of −8.

4) x + 3 = −11
If x = −8, then −8 + 3 ≠ −11 (which is −5 ≠ −11). So, this equation does not have a solution of −8.

The equation with a solution of −8 is:

x − 4 = −12
