Answer:
The value of the equation for y is [tex]y=\frac{a}{9-3x}[/tex].
Step-by-step explanation:
Consider the provided equation.
[tex]a=9y-3yx[/tex]
We need to solve the equation for y.
Take common y from right side.
[tex]a=y(9-3x)[/tex]
Divide both the sides by 9-3x.
[tex]\frac{a}{9-3x}=\frac{y(9-3x)}{9-3x}[/tex]
[tex]y=\frac{a}{9-3x}[/tex]
Hence, the value of the equation for y is [tex]y=\frac{a}{9-3x}[/tex].
