Answer: Yes
Explanation: Here, we want to determine if -24 is a solution for the equation -16 + 2x = -64. We can do this by simply plugging in -24 for x. If the statement holds true when -24 is plugged in for x, then -24 is a solution.
Plugging in -24 for x, we have -16 + 2(-24) = -64.
2(-24) is -48 so we have -16 + (-48) = -64.
-16 + (-48) is equal to -64 so we have -64 = -64.
-64 = -64 is a true statement so yes,
-24 is a solution for the equation -16 + 2x = -64.
