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

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

Simplifying
3(a + -4b) + -2(a + 4b) = 0
(a * 3 + -4b * 3) + -2(a + 4b) = 0
(3a + -12b) + -2(a + 4b) = 0
3a + -12b + (a * -2 + 4b * -2) = 0
3a + -12b + (-2a + -8b) = 0

Reorder the terms:
3a + -2a + -12b + -8b = 0

Combine like terms: 3a + -2a = 1a
1a + -12b + -8b = 0

Combine like terms: -12b + -8b = -20b
1a + -20b = 0

Solving
1a + -20b = 0

Solving for variable 'a'.

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

Add '20b' to each side of the equation.
1a + -20b + 20b = 0 + 20b

Combine like terms: -20b + 20b = 0
1a + 0 = 0 + 20b
1a = 0 + 20b
Remove the zero:
1a = 20b

Divide each side by '1'.
a = 20b

Simplifying
a = 20b
