Question

17=-5(3+w)+7 answer right and get a medal!

Answer 1

w=-5

Answer 2

17 = -5(3 + w) + 7 --multiply -5 through the parenthesis)
17 = - 15 - 5w + 7 -- get the 5w on the other side, so add 5w to both sides)
17 + 5w = -15 - 5w + 5w + 7 (combine like terms)
17 + 5w = - 8 (now get the 17 to the other side by subtracting 17)
17 - 17 + 5w = -8 - 17
5w = - 25 (divide by 5 to get w by itself)
5w/5 = -25/5
w = - 5
