What is the sum of 3m + 7y + 5 - m - 6y?

3m + 7y + 5 + - 1m + - 6y = 0

Reorder the terms:5 + 3m + - 1m + 7y + - 6y = 0

Combine like terms: 3m + - 1m = 2m5 + 2m + 7y + - 6y = 0

Combine like terms: 7y + - 6y = 1y5 + 2m + 1y = 0

Solving5 + 2m + 1y = 0

Solving for variable m'.

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

Add '-5' to each side of the equation. 5 + 2m + - 5 + 1y = 0 + - 5

Reorder the terms:5 + - 5 + 2m + 1y = 0 + - 5

Combine like terms: 5 + - 5 = 00 + 2m + 1y = 0 + - 52m + 1y = 0 + - 5

Combine like terms: 0 + - 5 = - 52m + 1y = - 5

Add '-1y' to each side of the equation. 2m + 1y + - 1y = - 5 + - 1y

Combine like terms: 1y + - 1y = 02m + 0 = - 5 + - 1y2m = - 5 + - 1y

Divide each side by '2'. m = - 2.5 + - 0.5y

Roots m=-2.5 + - 0.5y

Simplify the following:3 m + 7 y + 5 - m - 6 y

Grouping like terms, 3 m + 7 y + 5 - m - 6 y = (7 y - 6 y) + (3 m - m) + 5: (7 y - 6 y) + (3 m - m) + 5

7 y - 6 y = y:y + (3 m - m) + 5

3 m - m = 2 m:Answer: y + 2 m + 5

Not sure what you need so I gave you Simplification and Roots.
