Solve the following equation
1200-40w=120+50w
Solve for w
1200 - 40w = 120 + 50w
Group variables
Group our variables -40w and 50w
subtract 50w from both sides
-40w + 1200 - 50w = 50w + 120 - 50w
Cancel 50w on the right side:
-90w + 1200 = 120
Divide each side by 1200
Group constants
Group our constants 1200 and 120.
subtract 1200 from both sides
-90w + 1200 - 1200 = 120 - 1200
Cancel 1200 on the left side:
-90w = -1080
Divide each side of the equation by -90
w = 12
Final Answer
w = 12
