which of following equations has a solution of -8

Answer 1

In order to determine which equation has a solution of -8, we need to look at each equation and substitute -8 for the variable.

Let's evaluate each equation:

1. 3x + 5 = -8
Substituting -8 for x:
3(-8) + 5 = -8
-24 + 5 = -8
-19 ≠ -8
This equation does not have a solution of -8.

2. 2x - 10 = -8
Substituting -8 for x:
2(-8) - 10 = -8
-16 - 10 = -8
-26 ≠ -8
This equation does not have a solution of -8.

3. x^2 + 8 = -8
Substituting -8 for x:
(-8)^2 + 8 = -8
64 + 8 = -8
72 ≠ -8
This equation does not have a solution of -8.

4. 4x + 32 = -8
Substituting -8 for x:
4(-8) + 32 = -8
-32 + 32 = -8
0 ≠ -8
This equation does not have a solution of -8.

Therefore, none of the given equations has a solution of -8.
