Step-by-step explanation:
Simplifying
m + n = 14
Solving
m + n = 14
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-1n' to each side of the equation.
m + n + -1n = 14 + -1n
Combine like terms: n + -1n = 0
m + 0 = 14 + -1n
m = 14 + -1n
Simplifying
m = 14 + -1n
Answer:
so you would need to solve the variable for m
then add -1n to each side: m+n+-1n=14+-1n
then combine like terms: n+-1n=0
m+0=14+-1n
then just simply:m=14+-1n
