-(-4u+y)-4(y-4u)=

Solution for -(-4u+y)-4(y-4u)= equation:

Simplifying
-1(-4u + y) + -4(y + -4u) = 0
(-4u * -1 + y * -1) + -4(y + -4u) = 0
(4u + -1y) + -4(y + -4u) = 0

Reorder the terms:
4u + -1y + -4(-4u + y) = 0
4u + -1y + (-4u * -4 + y * -4) = 0
4u + -1y + (16u + -4y) = 0

Reorder the terms:
4u + 16u + -1y + -4y = 0

Combine like terms: 4u + 16u = 20u
20u + -1y + -4y = 0

Combine like terms: -1y + -4y = -5y
20u + -5y = 0

Solving
20u + -5y = 0

Solving for variable 'u'.

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

Add '5y' to each side of the equation.
20u + -5y + 5y = 0 + 5y

Combine like terms: -5y + 5y = 0
20u + 0 = 0 + 5y
20u = 0 + 5y
Remove the zero:
20u = 5y

Divide each side by '20'.
u = 0.25y

Simplifying
u = 0.25y
