Question

What is the answer to this equation Зу-х=9??

Answer 1

Your answer is x = -9+3y

Answer 2

`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`.
