3(a+b)-3(a-b)=

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

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

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

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

Combine like terms: 3b + 3b = 6b
6b = 0

Solving
6b = 0
