Solution for (4u-3v+9w)-4(-4u+2v-6w)= equation:


Simplifying
(4u + -3v + 9w) + -4(-4u + 2v + -6w) = 0

Remove parenthesis around (4u + -3v + 9w)
4u + -3v + 9w + -4(-4u + 2v + -6w) = 0
4u + -3v + 9w + (-4u * -4 + 2v * -4 + -6w * -4) = 0
4u + -3v + 9w + (16u + -8v + 24w) = 0

Reorder the terms:
4u + 16u + -3v + -8v + 9w + 24w = 0

Combine like terms: 4u + 16u = 20u
20u + -3v + -8v + 9w + 24w = 0

Combine like terms: -3v + -8v = -11v
20u + -11v + 9w + 24w = 0

Combine like terms: 9w + 24w = 33w
20u + -11v + 33w = 0

Solving
20u + -11v + 33w = 0

Solving for variable 'u'.

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

Add '11v' to each side of the equation.
20u + -11v + 11v + 33w = 0 + 11v

Combine like terms: -11v + 11v = 0
20u + 0 + 33w = 0 + 11v
20u + 33w = 0 + 11v
Remove the zero:
20u + 33w = 11v

Add '-33w' to each side of the equation.
20u + 33w + -33w = 11v + -33w
