X+8=-2 i think its -10 but plz verify

Isolate the x. Note the equal sign. What you do to one side, you do to the other.

Subtract 8 from both sides

x + 8 (-8) = -2 (-8)

x = -2 - 8

Combine

x = -10

-10 is your answer for x

hope this helps

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x

unlimited solutions.
