Solution for 3u+6v-2(3u-7v+2w)= equation:


Simplifying
3u + 6v + -2(3u + -7v + 2w) = 0
3u + 6v + (3u * -2 + -7v * -2 + 2w * -2) = 0
3u + 6v + (-6u + 14v + -4w) = 0

Reorder the terms:
3u + -6u + 6v + 14v + -4w = 0

Combine like terms: 3u + -6u = -3u
-3u + 6v + 14v + -4w = 0

Combine like terms: 6v + 14v = 20v
-3u + 20v + -4w = 0

Solving
-3u + 20v + -4w = 0

Solving for variable 'u'.

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

Add '-20v' to each side of the equation.
-3u + 20v + -20v + -4w = 0 + -20v

Combine like terms: 20v + -20v = 0
-3u + 0 + -4w = 0 + -20v
-3u + -4w = 0 + -20v
Remove the zero:
-3u + -4w = -20v

Add '4w' to each side of the equation.
-3u + -4w + 4w = -20v + 4w

Combine like terms: -4w + 4w = 0
-3u + 0 = -20v + 4w
-3u = -20v + 4w

Divide each side by '-3'.
u = 6.666666667v + -1.333333333w

Simplifying
u = 6.666666667v + -1.333333333w
