Enter Equation or Inequality

Solve the following equation


Solve for m

0.5m + m + m - 5 = 100

Group the m terms on the left:

(0.5 + 1 + 1)m = 2.5m

Form modified equation

2.5m - 5 = + 100

Group constants

Group our constants -5 and 100.
add 5 to both sides

2.5m - 5 + 5 = 100 + 5

Cancel 5 on the left side:

2.5m = 105

Divide each side of the equation by 2.5


m = 42

Final Answer

m = 42

What is the Answer?
m = 42
