Enter Equation or Inequality

Solve the following equation


Solve for m

m + 400 + m = 3600

Group the m terms on the left:

(1 + 1)m = 2m

Form modified equation

2m + 400 = + 3600

Group constants

Group our constants 400 and 3600.
subtract 400 from both sides

2m + 400 - 400 = 3600 - 400

Cancel 400 on the left side:

2m = 3200

Divide each side of the equation by 2


m = 1600

Final Answer

m = 1600

What is the Answer?
m = 1600
