Solution for -5(a-b)-(a-b)+8(a-b)= equation:


Simplifying
-5(a + -1b) + -1(a + -1b) + 8(a + -1b) = 0
(a * -5 + -1b * -5) + -1(a + -1b) + 8(a + -1b) = 0
(-5a + 5b) + -1(a + -1b) + 8(a + -1b) = 0
-5a + 5b + (a * -1 + -1b * -1) + 8(a + -1b) = 0
-5a + 5b + (-1a + 1b) + 8(a + -1b) = 0
-5a + 5b + -1a + 1b + (a * 8 + -1b * 8) = 0
-5a + 5b + -1a + 1b + (8a + -8b) = 0

Reorder the terms:
-5a + -1a + 8a + 5b + 1b + -8b = 0

Combine like terms: -5a + -1a = -6a
-6a + 8a + 5b + 1b + -8b = 0

Combine like terms: -6a + 8a = 2a
2a + 5b + 1b + -8b = 0

Combine like terms: 5b + 1b = 6b
2a + 6b + -8b = 0

Combine like terms: 6b + -8b = -2b
