-2(u+1)=2u-6+2(7u+3)

Solution for -2(u+1)=2u-6+2(7u+3) equation:

Simplifying
-2(u + 1) = 2u + -6 + 2(7u + 3)

Reorder the terms:
-2(1 + u) = 2u + -6 + 2(7u + 3)
(1 * -2 + u * -2) = 2u + -6 + 2(7u + 3)
(-2 + -2u) = 2u + -6 + 2(7u + 3)

Reorder the terms:
-2 + -2u = 2u + -6 + 2(3 + 7u)
-2 + -2u = 2u + -6 + (3 * 2 + 7u * 2)
-2 + -2u = 2u + -6 + (6 + 14u)

Reorder the terms:
-2 + -2u = -6 + 6 + 2u + 14u

Combine like terms: -6 + 6 = 0
-2 + -2u = 0 + 2u + 14u
-2 + -2u = 2u + 14u

Combine like terms: 2u + 14u = 16u
-2 + -2u = 16u

Solving
-2 + -2u = 16u

Solving for variable 'u'.

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

Add '-16u' to each side of the equation.
-2 + -2u + -16u = 16u + -16u

Combine like terms: -2u + -16u = -18u
-2 + -18u = 16u + -16u

Combine like terms: 16u + -16u = 0
-2 + -18u = 0

Add '2' to each side of the equation.
-2 + 2 + -18u = 0 + 2

Combine like terms: -2 + 2 = 0
0 + -18u = 0 + 2
-18u = 0 + 2

Combine like terms: 0 + 2 = 2
-18u = 2

Divide each side by '-18'.
u = -0.1111111111

Simplifying
u = -0.1111111111
