3× + y = 8, 4× - 3y=2

x=2

y=2

Step-by-step explanation:

You can use the process of elimination

x can't be 3 because than the first question would be 9+y=8 which is even bigger than the answer.

So now, we try 2. x=2

6+y=8 which =

6+2=8

So y must be two

Then we try it on the

Second one.

8-6=2 which makes sense.

Hope it helps
