Answer:

x = -6 + 3y or x = 3y - 6

Explanation:

-3x = 18 - 9y

x = (18 - 9y) / -3

x = -6 + 3y or x = 3y - 6

Answer: x=-6+3y and y=2+
(x)/(3).

Step-by-step explanation: First, let's solve for x. Our goal is to make x alone, so therefore we can subtract 9y, which will make the equation look like this: -3x=-9y+18, and then we can divide both sides by -3 because what ever you do on one side, you have to do to the other side, and therefore would get x=-6+3y. To solve for y, we are getting y alone, so we can add 3x to both sides to make the equation look like this: 9y=3x+18, and then we can divide both sides by 9, getting your answer of y=2+
(x)/(3). If you need more help or clarification let me know!
