2(a+b)+2(2+b)=

Solution for 2(a+b)+2(2+b)= equation:

Simplifying
2(a + b) + 2(2 + b) = 0
(a * 2 + b * 2) + 2(2 + b) = 0
(2a + 2b) + 2(2 + b) = 0
2a + 2b + (2 * 2 + b * 2) = 0
2a + 2b + (4 + 2b) = 0

Reorder the terms:
4 + 2a + 2b + 2b = 0

Combine like terms: 2b + 2b = 4b
4 + 2a + 4b = 0

Solving
4 + 2a + 4b = 0

Solving for variable 'a'.

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

Add '-4' to each side of the equation.
4 + 2a + -4 + 4b = 0 + -4

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

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

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

Add '-4b' to each side of the equation.
2a + 4b + -4b = -4 + -4b

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

Divide each side by '2'.
a = -2 + -2b

Simplifying
a = -2 + -2b
