Question

Solve a=9y+3yx for y

Answer 1

(a=9y+3yx)/y
a/y=9+3x
y=a/(9+3x)

Answer 2

`y=(a)/((9+3x))`

Explanation:

we have

`A=9y+3yx`

Solve for y

That means -----> isolate the variable y

Step 1

Factor the variable y in the right side

`a=y(9+3x)`

Step 2

Divide by
`(9+3x)` both sides

`a/(9+3x)=y(9+3x)/(9+3x)`

Step 3

Simplify

`y=(a)/((9+3x))`
