8/v + 9/x=y Solve for v

The answer is v = - 8x/-xy+9

Here is the step by step process (This is going to be long):

1. 9v+8x=vxy

Multiply both sides by vx

2. 9v+8x+-vxy=vxy+-vxy

-vxy+9v+8x=0

Add - vxy to both sides

3. - vxy+9v+8x+-8x=0+-8x

-vxy+9v=-8x

Add - 8x to both sides

4. v (-xy+9) = -8x

Factor out the variable v

5. v (-xy+9) / -xy+9 = - 8x/-xy+9

v = - 8x/-xy+9

Divide both sides by - xy+9
