Which of the following equations has a solution of -8? (1 point)
x - 10 = 2
x + 3 = - 11
x - 4 = - 12
x - 8 = 0
The equation x - 8 = 0 has a solution of x = 8.
To determine which equation has a solution of -8, we can substitute -8 into each equation and see if it satisfies the equation.
1. x - 10 = 2
Substituting -8 into the equation: -8 - 10 = 2
This simplifies to -18 = 2, which is not true.
2. x + 3 = - 11
Substituting -8 into the equation: -8 + 3 = - 11
This simplifies to -5 = - 11, which is not true.
3. x - 4 = - 12
Substituting -8 into the equation: -8 - 4 = - 12
This simplifies to -12 = - 12, which is true.
4. x - 8 = 0
Substituting -8 into the equation: -8 - 8 = 0
This simplifies to -16 = 0, which is not true.
Therefore, the equation x - 4 = - 12 has a solution of -8.
To find the equation that has a solution of -8, we need to substitute -8 into each equation and check which one holds true. Let's evaluate each equation using -8:
1) x - 10 = 2:
Substituting x = -8, we have -8 - 10 = 2 ==> -18 = 2, which is not true.
2) x + 3 = -11:
Substituting x = -8, we have -8 + 3 = -11 ==> -5 = -11, which is not true.
3) x - 4 = -12:
Substituting x = -8, we have -8 - 4 = -12 ==> -12 = -12, which is true.
4) x - 8 = 0:
Substituting x = -8, we have -8 - 8 = 0 ==> -16 = 0, which is not true.
Therefore, the equation that has a solution of -8 is: x - 4 = -12.
