# m+12+2m+12+4m+12=78

## Enter Equation or Inequality

Solve the following equation
m+12+2m+12+4m+12=78

Solve for m
m + 12 + 2m + 12 + 4m + 12 = 78

## Group the m terms on the left:

(1 + 2 + 4)m = 7m

## Group the constants on the left:

12 + 12 + 12 = 36

7m + 36 = + 78

## Group constants:

Group our constants 36 and 78.
subtract 36 from both sides
7m + 36 - 36 = 78 - 36

7m = 42

## Divide each side of the equation by 7

 7m 7
 =
 42 7

m = 6

m = 6
