M-n-(-a)=

Solution for M-n-(-a)= equation:

Simplifying
M + -1n + -1(-1a) = 0

Remove parenthesis around (-1a)
M + -1n + -1 * -1a = 0

Multiply -1 * -1
M + -1n + 1a = 0

Reorder the terms:
M + 1a + -1n = 0

Solving
M + 1a + -1n = 0

Solving for variable 'M'.

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

Add '-1a' to each side of the equation.
M + 1a + -1a + -1n = 0 + -1a

Combine like terms: 1a + -1a = 0
M + 0 + -1n = 0 + -1a
M + -1n = 0 + -1a
Remove the zero:
M + -1n = -1a

Add 'n' to each side of the equation.
M + -1n + n = -1a + n

Combine like terms: -1n + n = 0
M + 0 = -1a + n
M = -1a + n

Simplifying
M = -1a + n
