Enter Equation or Inequality

Solve the following equation

1.80m+3=12

Solve for m

1.80m + 3 = 12

Divide each side by 1.80

1.80m
1.80
=
  
3
1.80

Group constants

Group our constants 3 and 12.
subtract 3 from both sides

1.80m + 3 - 3 = 12 - 3

Cancel 3 on the left side:

1.80m = 9

Divide each side of the equation by 1.80

1.80m
1.80
=
  
9
1.80

m = 5

Final Answer


m = 5
