-(-a-b+2c)=

Solution for -(-a-b+2c)= equation:

Simplifying
-1(-1a + -1b + 2c) = 0
(-1a * -1 + -1b * -1 + 2c * -1) = 0
(1a + 1b + -2c) = 0

Solving
1a + 1b + -2c = 0

Solving for variable 'a'.

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

Add '-1b' to each side of the equation.
1a + 1b + -1b + -2c = 0 + -1b

Combine like terms: 1b + -1b = 0
1a + 0 + -2c = 0 + -1b
1a + -2c = 0 + -1b
Remove the zero:
1a + -2c = -1b

Add '2c' to each side of the equation.
1a + -2c + 2c = -1b + 2c

Combine like terms: -2c + 2c = 0
1a + 0 = -1b + 2c
1a = -1b + 2c

Divide each side by '1'.
a = -1b + 2c

Simplifying
a = -1b + 2c
