Enter Equation or Inequality

Solve the following equation


Solve for w

6w + 8 + 2w = 72

Group the w terms on the left:

(6 + 2)w = 8w

Form modified equation

8w + 8 = + 72

Group constants

Group our constants 8 and 72.
subtract 8 from both sides

8w + 8 - 8 = 72 - 8

Cancel 8 on the left side:

8w = 64

Divide each side of the equation by 8


w = 8

Final Answer

w = 8

What is the Answer?
w = 8
