-3(a+4b)+2(2b-a)=

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

Simplifying
-3(a + 4b) + 2(2b + -1a) = 0
(a * -3 + 4b * -3) + 2(2b + -1a) = 0
(-3a + -12b) + 2(2b + -1a) = 0

Reorder the terms:
-3a + -12b + 2(-1a + 2b) = 0
-3a + -12b + (-1a * 2 + 2b * 2) = 0
-3a + -12b + (-2a + 4b) = 0

Reorder the terms:
-3a + -2a + -12b + 4b = 0

Combine like terms: -3a + -2a = -5a
-5a + -12b + 4b = 0

Combine like terms: -12b + 4b = -8b
-5a + -8b = 0

Solving
-5a + -8b = 0

Solving for variable 'a'.

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

Add '8b' to each side of the equation.
-5a + -8b + 8b = 0 + 8b

Combine like terms: -8b + 8b = 0
-5a + 0 = 0 + 8b
-5a = 0 + 8b
Remove the zero:
-5a = 8b

Divide each side by '-5'.
a = -1.6b

Simplifying
a = -1.6b
