Simplifying
M + -3 = 13.8
Reorder the terms:
-3 + M = 13.8
Solving
-3 + M = 13.8
Solving for variable 'M'.
Move all terms containing M to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 3 + M = 13.8 + 3
Combine like terms: -3 + 3 = 0
0 + M = 13.8 + 3
M = 13.8 + 3
Combine like terms: 13.8 + 3 = 16.8
M = 16.8
Simplifying
M = 16.8
