-2(4a-6b)-(a-b)=

Solution for -2(4a-6b)-(a-b)= equation:

Simplifying
-2(4a + -6b) + -1(a + -1b) = 0
(4a * -2 + -6b * -2) + -1(a + -1b) = 0
(-8a + 12b) + -1(a + -1b) = 0
-8a + 12b + (a * -1 + -1b * -1) = 0
-8a + 12b + (-1a + 1b) = 0

Reorder the terms:
-8a + -1a + 12b + 1b = 0

Combine like terms: -8a + -1a = -9a
-9a + 12b + 1b = 0

Combine like terms: 12b + 1b = 13b
-9a + 13b = 0

Solving
-9a + 13b = 0

Solving for variable 'a'.

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

Add '-13b' to each side of the equation.
-9a + 13b + -13b = 0 + -13b

Combine like terms: 13b + -13b = 0
-9a + 0 = 0 + -13b
-9a = 0 + -13b
Remove the zero:
-9a = -13b

Divide each side by '-9'.
a = 1.444444444b

Simplifying
a = 1.444444444b
