Solution for -5(a-b)-2(a-b)+8(a-b)= equation:


Simplifying
-5(a + -1b) + -2(a + -1b) + 8(a + -1b) = 0
(a * -5 + -1b * -5) + -2(a + -1b) + 8(a + -1b) = 0
(-5a + 5b) + -2(a + -1b) + 8(a + -1b) = 0
-5a + 5b + (a * -2 + -1b * -2) + 8(a + -1b) = 0
-5a + 5b + (-2a + 2b) + 8(a + -1b) = 0
-5a + 5b + -2a + 2b + (a * 8 + -1b * 8) = 0
-5a + 5b + -2a + 2b + (8a + -8b) = 0
