Solution for 3(u+w)+-5(u-w)= equation:


Simplifying
3(u + w) + -5(u + -1w) = 0
(u * 3 + w * 3) + -5(u + -1w) = 0
(3u + 3w) + -5(u + -1w) = 0
3u + 3w + (u * -5 + -1w * -5) = 0
3u + 3w + (-5u + 5w) = 0

Reorder the terms:
3u + -5u + 3w + 5w = 0

Combine like terms: 3u + -5u = -2u
-2u + 3w + 5w = 0

Combine like terms: 3w + 5w = 8w
-2u + 8w = 0

Solving
-2u + 8w = 0

Solving for variable 'u'.

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

Add '-8w' to each side of the equation.
-2u + 8w + -8w = 0 + -8w

Combine like terms: 8w + -8w = 0
-2u + 0 = 0 + -8w
-2u = 0 + -8w
Remove the zero:
-2u = -8w

Divide each side by '-2'.
u = 4w

Simplifying
u = 4w
