To find the equation with a solution of -8, we need to substitute -8 for x in each equation and see which one gives us a true statement.
1. x - 10 = 2
Substituting x = -8, we have: -8 - 10 = 2, which is not true.
2. x + 3 = -11
Substituting x = -8, we have: -8 + 3 = -11, which is not true.
3. x - 4 = -12
Substituting x = -8, we have: -8 - 4 = -12, which is true.
4. x - 8 = 0
Substituting x = -8, we have: -8 - 8 = 0, which is not true.
Therefore, the equation that has a solution of -8 is x - 4 = -12.
Which of the following equations has a solution of -8?
1. x - 10 = 2
2. x + 3 = -11
3. x - 4 = -12
4. x - 8 = 0
