=-(3a-2b)-3(b-a)

Solution for =-(3a-2b)-3(b-a) equation:

Simplifying
0 = -1(3a + -2b) + -3(b + -1a)
0 = (3a * -1 + -2b * -1) + -3(b + -1a)
0 = (-3a + 2b) + -3(b + -1a)

Reorder the terms:
0 = -3a + 2b + -3(-1a + b)
0 = -3a + 2b + (-1a * -3 + b * -3)
0 = -3a + 2b + (3a + -3b)

Reorder the terms:
0 = -3a + 3a + 2b + -3b

Combine like terms: -3a + 3a = 0
0 = 0 + 2b + -3b
0 = 2b + -3b

Combine like terms: 2b + -3b = -1b
0 = -1b

Solving
0 = -1b

Solving for variable 'b'.

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

Add 'b' to each side of the equation.
0 + b = -1b + b
Remove the zero:
b = -1b + b

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

Simplifying
b = 0
