Which of the following equations has a solution of -8?

Question

x-4=-12
x+3=-11
x-8=0
x-10=2

Answer 1

To find which equation has a solution of -8, we can substitute -8 into each equation and see which one is true.

1) x-4=-12
Replacing x with -8:
-8 - 4 = -12
-12 = -12
This equation is true, so -8 is a solution to this equation.

2) x+3=-11
Replacing x with -8:
-8 + 3 = -11
-5 = -11
This equation is not true, so -8 is not a solution to this equation.

3) x-8=0
Replacing x with -8:
-8 - 8 = 0
-16 = 0
This equation is not true, so -8 is not a solution to this equation.

4) x-10=2
Replacing x with -8:
-8 - 10 = 2
-18 = 2
This equation is not true, so -8 is not a solution to this equation.

Therefore, the equation x-4=-12 has a solution of -8.
