Answer:
y =
Explanation:
A = 9y + 3yx for y,
The first step is to factor out the terms on the right-hand side of the equation:
A = 3y(3 + x)
Next, divide both sides by 3(3 + x) to isolate y:
or rewrite this as:
Since 3(3 + x) cancel out on the right-hand side of the equation, the only variable left will be the unknown, y.
Therefore, the final answer is:
