2(3a+b)-2(a-b)=

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

Simplifying
2(3a + b) + -2(a + -1b) = 0
(3a * 2 + b * 2) + -2(a + -1b) = 0
(6a + 2b) + -2(a + -1b) = 0
6a + 2b + (a * -2 + -1b * -2) = 0
6a + 2b + (-2a + 2b) = 0

Reorder the terms:
6a + -2a + 2b + 2b = 0

Combine like terms: 6a + -2a = 4a
4a + 2b + 2b = 0

Combine like terms: 2b + 2b = 4b
4a + 4b = 0

Solving
4a + 4b = 0

Solving for variable 'a'.

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

Add '-4b' to each side of the equation.
4a + 4b + -4b = 0 + -4b

Combine like terms: 4b + -4b = 0
4a + 0 = 0 + -4b
4a = 0 + -4b
Remove the zero:
4a = -4b

Divide each side by '4'.
a = -1b

Simplifying
a = -1b
