Answer:


x=-9+3y.

Explanation:

The answer(s) of an equation expressed in terms of y and x is tipically found by solving the equation for x. Let's do that in the following steps:

1. Write the expression.


3y-x=9

2. Substract 3y from both sides.


-3y+3y-x=9-3y\\ \\-x=9-3y

3. Multiply both sides by -1.


(-1)(-x)=(9-3y)(-1)\\ \\x=-9+3y

4. Express the result.


x=-9+3y.
