Answer:(2, 8)

Step-by-step explanation: What I did was this:

y=4x(3)

y=3x+2(4)

So, we then have:

y=12x

y=12x+8

Then, I subtracted y=12x from y=12x+8 so I got y=8

Now that we know what y is we can plug it into one of the original equations:

8=4x

We know that 4 * 2 = 8, so x = 2.

Now we can check our work with the other equation:

8 = 3 (2) + 2

8 = 6 + 2

8 = 8

Our answer was right, (2, 8)
