Question

Rearrange the equation so u is the independent variable. 4u+8w=-3u+2w4u+8w=−3u+2w

Answer 1

Answer:

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
