-a(b+1)=ab-a

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

Simplifying
-1a(b + 1) = ab + -1a

Reorder the terms:
-1a(1 + b) = ab + -1a
(1 * -1a + b * -1a) = ab + -1a
(-1a + -1ab) = ab + -1a

Reorder the terms:
-1a + -1ab = -1a + ab

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

Combine like terms: -1a + a = 0
0 + -1ab = -1a + a + ab
-1ab = -1a + a + ab

Combine like terms: -1a + a = 0
-1ab = 0 + ab
-1ab = ab

Solving
-1ab = ab

Solving for variable 'a'.
