Solve the following equation

800-20w=500+30w

Solve for w

800 - 20w = 500 + 30w

Group variables

Group our variables -20w and 30w
subtract 30w from both sides

-20w + 800 - 30w = 30w + 500 - 30w

Cancel 30w on the right side:

-50w + 800 = 500

Group constants

Group our constants 800 and 500.
subtract 800 from both sides

-50w + 800 - 800 = 500 - 800

Cancel 800 on the left side:

-50w = -300

Divide each side of the equation by -50

-50w
-50
=
  
-300
-50

w = 6

Final Answer

w = 6





What is the Answer?
w = 6
