Question

How do u slove it 9=v+4/v+12

Answer 1

step 1

Write the equation.

`9\text{ = }\frac{v\text{ + 4}}{v\text{ + 12}}`

Step 2

Multiply both sides of the equation by v + 12.

`\begin{gathered} 9*(v+12)\text{ = \lparen v+12\rparen}*(v+4)/(v+12) \\ \\ Cancel\text{ out common factors:} \\ \\ 9v\text{ + 108 = v + 4} \\ \\ 9v\text{ - v = 4 - 108} \\ \\ 8v\text{ = =-104} \\ \\ Divide\text{ both sides by 8:} \\ \\ (8v)/(8)\text{ = }(-104)/(8) \\ \\ v\text{ = -13} \end{gathered}`

Final answer

v = -13
