-9w+17=7-4w Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! -9w + 17 = 7 - 4w
we want to get unknown on the left and the numerical values on the right
Add 4w to both sides, results
-9w + 4w + 17 = 7
:
Subtract 17 from both sides, results:
-9w + 4w = 7 - 17
;
combine like terms
-5w = -10
;
The variable always has to be positive, multiply both sides by -1
5w = +10
divide both sides by 5
w =
w = 2
:
:
Check solution in original equation, check for equality
-9w + 17 = 7 - 4w
-9(2) + 17 = 7 - 4(2)
-18 + 17 = 7 - 8
-1 = -1; confirms our solution
