Solution for 3u+9v-6(3u-7v+5w)= equation:


Simplifying
3u + 9v + -6(3u + -7v + 5w) = 0
3u + 9v + (3u * -6 + -7v * -6 + 5w * -6) = 0
3u + 9v + (-18u + 42v + -30w) = 0

Reorder the terms:
3u + -18u + 9v + 42v + -30w = 0

Combine like terms: 3u + -18u = -15u
-15u + 9v + 42v + -30w = 0

Combine like terms: 9v + 42v = 51v
-15u + 51v + -30w = 0

Solving
-15u + 51v + -30w = 0

Solving for variable 'u'.

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

Add '-51v' to each side of the equation.
-15u + 51v + -51v + -30w = 0 + -51v

Combine like terms: 51v + -51v = 0
-15u + 0 + -30w = 0 + -51v
-15u + -30w = 0 + -51v
Remove the zero:
-15u + -30w = -51v

Add '30w' to each side of the equation.
-15u + -30w + 30w = -51v + 30w

Combine like terms: -30w + 30w = 0
-15u + 0 = -51v + 30w
-15u = -51v + 30w

Divide each side by '-15'.
u = 3.4v + -2w

Simplifying
u = 3.4v + -2w
