( 9 ÷ 3 ) x 2 = 3 x 2 = 6 marbles ;
Answer:
x is equal to negative one, and y is equal to negative four.
Step-by-step explanation:
You can do this by solving one of the equations by either x or y, then substituting it into the other. Let's solve the second one for y:

Now we'll substitute that into the first equation:

So we now know that x is equal to -1. We can simply substitute that into one of the original equations to find y:

We now know that x is equal to -1, and y is equal to -4. We can also check our answer by plugging that -4 into the other equation, and see if we still get -1:

So we know that our answer is correct.
