Enter Equation or Inequality

Solve the following equation


Solve for w

20 + 10w = 1000 - 15w

Group variables

Group our variables 10w and -15w
add 15w to both sides

10w + 20 + 15w = -15w + 1000 + 15w

Cancel -15w on the right side:

25w + 20 = 1000

Group constants

Group our constants 20 and 1000.
subtract 20 from both sides

25w + 20 - 20 = 1000 - 20

Cancel 20 on the left side:

25w = 980

Divide each side of the equation by 25


w = 39.2

Final Answer

w = 39.2

What is the Answer?
w = 39.2
