 # 0.5m+m+m-5=100

## Enter Equation or Inequality

Solve the following equation
0.5m+m+m-5=100

Solve for m
0.5m + m + m - 5 = 100

## Group the m terms on the left:

(0.5 + 1 + 1)m = 2.5m

2.5m - 5 = + 100

## Group constants

Group our constants -5 and 100.
2.5m - 5 + 5 = 100 + 5

2.5m = 105

## Divide each side of the equation by 2.5

 2.5m 2.5
 =
 105 2.5

m = 42

m = 42
