8 - (x+3) = 11 solve for x

If you're subtracting to add, you must subtract a negative number to be able to solve for x. So 8 - (-6+3) = 11. x = - 6.

First multiply - 1 by everything in the parenthesis, so it would be

8 - x - 3 = 11

combine like terms (8 and - 3)

5 - x = 11

subtract 5 from both sides

-x = 11-5

-x = 6

divide both sides by - 1 and you get

x = - 6
