Solve the following equation

20m+100=80+30m

Solve for m

20m + 100 = 80 + 30m

Group variables

Group our variables 20m and 30m
subtract 30m from both sides

20m + 100 - 30m = 30m + 80 - 30m

Cancel 30m on the right side:

-10m + 100 = 80

Divide each side by 20

20m
20
=
  
100
20

Group constants

Group our constants 100 and 80.
subtract 100 from both sides

-10m + 100 - 100 = 80 - 100

Cancel 100 on the left side:

-10m = -20

Divide each side of the equation by -10

-10m
-10
=
  
-20
-10

m = 2

Final Answer


m = 2
