Question

Solve for y in a=9y+3yx

Answer 1

 hello : 
a=9y+3yx
y(9+3x) = a 
y = a/(9+3x).......9+3x ≠ 0

Answer 2

Answer:

$y=\frac{a}{(9+3x)}$

Step-by-step 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

$y=\frac{a}{(9+3x)}$
