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

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

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

Reorder the terms:
-2a + -2a + 6b + 1b = 0

Combine like terms: -2a + -2a = -4a
-4a + 6b + 1b = 0

Combine like terms: 6b + 1b = 7b
-4a + 7b = 0

Solving
-4a + 7b = 0

Solving for variable 'a'.

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

Add '-7b' to each side of the equation.
-4a + 7b + -7b = 0 + -7b

Combine like terms: 7b + -7b = 0
-4a + 0 = 0 + -7b
-4a = 0 + -7b
Remove the zero:
-4a = -7b

Divide each side by '-4'.
a = 1.75b

Simplifying
a = 1.75b
