Solution for 2u+8v-3(2u-5v+9w)= equation:


Simplifying
2u + 8v + -3(2u + -5v + 9w) = 0
2u + 8v + (2u * -3 + -5v * -3 + 9w * -3) = 0
2u + 8v + (-6u + 15v + -27w) = 0

Reorder the terms:
2u + -6u + 8v + 15v + -27w = 0

Combine like terms: 2u + -6u = -4u
-4u + 8v + 15v + -27w = 0

Combine like terms: 8v + 15v = 23v
-4u + 23v + -27w = 0

Solving
-4u + 23v + -27w = 0

Solving for variable 'u'.

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

Add '-23v' to each side of the equation.
-4u + 23v + -23v + -27w = 0 + -23v

Combine like terms: 23v + -23v = 0
-4u + 0 + -27w = 0 + -23v
-4u + -27w = 0 + -23v
Remove the zero:
-4u + -27w = -23v

Add '27w' to each side of the equation.
-4u + -27w + 27w = -23v + 27w

Combine like terms: -27w + 27w = 0
-4u + 0 = -23v + 27w
-4u = -23v + 27w

Divide each side by '-4'.
u = 5.75v + -6.75w

Simplifying
u = 5.75v + -6.75w
