3(m-3)-4(m+3)=o

Solution for 3(m-3)-4(m+3)=o equation:

Simplifying
3(m + -3) + -4(m + 3) = o

Reorder the terms:
3(-3 + m) + -4(m + 3) = o
(-3 * 3 + m * 3) + -4(m + 3) = o
(-9 + 3m) + -4(m + 3) = o

Reorder the terms:
-9 + 3m + -4(3 + m) = o
-9 + 3m + (3 * -4 + m * -4) = o
-9 + 3m + (-12 + -4m) = o

Reorder the terms:
-9 + -12 + 3m + -4m = o

Combine like terms: -9 + -12 = -21
-21 + 3m + -4m = o

Combine like terms: 3m + -4m = -1m
-21 + -1m = o

Solving
-21 + -1m = o

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '21' to each side of the equation.
-21 + 21 + -1m = 21 + o

Combine like terms: -21 + 21 = 0
0 + -1m = 21 + o
-1m = 21 + o

Divide each side by '-1'.
m = -21 + -1o

Simplifying
m = -21 + -1o
