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

Question

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

Answer 1

To find which equation has a solution of -8, we need to substitute -8 for X and see if the equation holds true.

1. X - 8 = 0
Substituting -8 for X: -8 - 8 = 0
Simplifying: -16 = 0
The equation does not hold true, so this equation does not have a solution of -8.

2. X - 4 = -12
Substituting -8 for X: -8 - 4 = -12
Simplifying: -12 = -12
The equation holds true, so this equation has a solution of -8.

3. X - 10 = 2
Substituting -8 for X: -8 - 10 = 2
Simplifying: -18 = 2
The equation does not hold true, so this equation does not have a solution of -8.

4. X + 3 = -11
Substituting -8 for X: -8 + 3 = -11
Simplifying: -5 = -11
The equation does not hold true, so this equation does not have a solution of -8.

Thus, only the equation X - 4 = -12 has a solution of -8.
