Solution for (a-b)-4(a-b)+(a-b)= equation:


Simplifying
(a + -1b) + -4(a + -1b) + (a + -1b) = 0

Remove parenthesis around (a + -1b)
a + -1b + -4(a + -1b) + (a + -1b) = 0
a + -1b + (a * -4 + -1b * -4) + (a + -1b) = 0
a + -1b + (-4a + 4b) + (a + -1b) = 0

Remove parenthesis around (a + -1b)
a + -1b + -4a + 4b + a + -1b = 0

Reorder the terms:
a + -4a + a + -1b + 4b + -1b = 0

Combine like terms: a + -4a = -3a
-3a + a + -1b + 4b + -1b = 0

Combine like terms: -3a + a = -2a
-2a + -1b + 4b + -1b = 0

Combine like terms: -1b + 4b = 3b
-2a + 3b + -1b = 0

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

Solving
-2a + 2b = 0

Solving for variable 'a'.

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

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

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

Divide each side by '-2'.
a = b

Simplifying
a = b
