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

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

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

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

Combine like terms: 4a + 3a = 7a
7a + -4b + -3b = 0

Combine like terms: -4b + -3b = -7b
7a + -7b = 0

Solving
7a + -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.
7a + -7b + 7b = 0 + 7b

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

Divide each side by '7'.
a = b

Simplifying
a = b
