Rearrange the equation so u is the independent variable.

4u+8w=-3u+2w4u+8w=-3u+2w

Step-by-step explanation:

4u + 8v = - 3u + 2v

Solving 4u + 8v = - 3u + 2v

Solving for variable 'u'.

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

Add '3u' to each side of the equation. 4u + 3u + 8v = - 3u + 3u + 2v

Combine like terms: 4u + 3u = 7u 7u + 8v = - 3u + 3u + 2v

Combine like terms: - 3u + 3u = 0 7u + 8v = 0 + 2v 7u + 8v = 2v

Add '-8v' to each side of the equation. 7u + 8v + - 8v = 2v + - 8v

Combine like terms: 8v + - 8v = 0 7u + 0 = 2v + - 8v 7u = 2v + - 8v

Combine like terms: 2v + - 8v = - 6v 7u = - 6v

Divide each side by '7'. u = - 0.8571428571v

Simplifying u = - 0.8571428571v
