Answer:
x = -11
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.
First, subtract 3 from both sides of the equation:
3 + x = -8
x + 3 (-3) = -8 (-3)
x = -8 - 3
Simplify:
x = -8 - 3
x = -11
x = -11 is your answer.

The answer is -11. If you +8 to -8 it would cancel out and since you added +8 to that side you have to add +8 to 3 which would make X -11.
