c+m+m+m+m+(-a)=5m-d-a

Solution for c+m+m+m+m+(-a)=5m-d-a equation:

Simplifying
c + m + m + m + m + (-1a) = 5m + -1d + -1a

Reorder the terms:
(-1a) + c + m + m + m + m = 5m + -1d + -1a

Combine like terms: m + m = 2m
(-1a) + c + 2m + m + m = 5m + -1d + -1a

Combine like terms: 2m + m = 3m
(-1a) + c + 3m + m = 5m + -1d + -1a

Combine like terms: 3m + m = 4m
(-1a) + c + 4m = 5m + -1d + -1a

Reorder the terms:
(-1a) + c + 4m = -1a + -1d + 5m

Add '(a)' to each side of the equation.
(-1a) + c + (a) + 4m = -1a + -1d + (a) + 5m
(-1a) + c + a + 4m = -1a + -1d + (a) + 5m

Reorder the terms:
(-1a) + a + c + 4m = -1a + -1d + (a) + 5m

Combine like terms: (-1a) + a = 0
0 + c + 4m = -1a + -1d + (a) + 5m
c + 4m = -1a + -1d + (a) + 5m
c + 4m = -1a + -1d + a + 5m

Reorder the terms:
c + 4m = -1a + a + -1d + 5m

Combine like terms: -1a + a = 0
c + 4m = 0 + -1d + 5m
c + 4m = -1d + 5m

Solving
c + 4m = -1d + 5m

Solving for variable 'c'.

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

Add '-4m' to each side of the equation.
c + 4m + -4m = -1d + 5m + -4m

Combine like terms: 4m + -4m = 0
c + 0 = -1d + 5m + -4m
c = -1d + 5m + -4m

Combine like terms: 5m + -4m = 1m
c = -1d + 1m

Simplifying
c = -1d + 1m
