Solution for -(-u+y)-2(y+u)= equation:


Simplifying
-1(-1u + y) + -2(y + u) = 0
(-1u * -1 + y * -1) + -2(y + u) = 0
(1u + -1y) + -2(y + u) = 0

Reorder the terms:
1u + -1y + -2(u + y) = 0
1u + -1y + (u * -2 + y * -2) = 0
1u + -1y + (-2u + -2y) = 0

1u + -2u + -1y + -2y = 0

Combine like terms: 1u + -2u = -1u
-1u + -1y + -2y = 0

Combine like terms: -1y + -2y = -3y
-1u + -3y = 0

Solving
-1u + -3y = 0

Solving for variable 'u'.

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