-1(a-b+c)=

Solution for -1(a-b+c)= equation:

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

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

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

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

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

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

Simplifying
a = b + -1c
