Solution for 2(a-b)+3(a-b)-4(a-b)=0 equation:


Simplifying
2(a + -1b) + 3(a + -1b) + -4(a + -1b) = 0
(a * 2 + -1b * 2) + 3(a + -1b) + -4(a + -1b) = 0
(2a + -2b) + 3(a + -1b) + -4(a + -1b) = 0
2a + -2b + (a * 3 + -1b * 3) + -4(a + -1b) = 0
2a + -2b + (3a + -3b) + -4(a + -1b) = 0
2a + -2b + 3a + -3b + (a * -4 + -1b * -4) = 0
2a + -2b + 3a + -3b + (-4a + 4b) = 0
