Question

Is x = -6 a solution to -2x - 4 = 8?

Answer 1

since it's x there is only 1 solution so you can just solve for x:

-2x = 12
x = 12/-2
x = -6

it is indeed a solution

Answer 2

plug it in and find out! if you get something funky then it isn't.

-2(-6)-4=8
12-4=8
8=8
since this is true, then -6 is a solution

Answer 3

Thanks, everyone! :)
