Answer:

x = 4 and y = 1

Step-by-step explanation:

3x+2y=14

2x-4y=4

We can solve them by canceling out one variable so we only have one variable left. Let's cancel out y by doubling the first equation. We get:

6x + 4y = 28

add that on to the second one and we get:

8x = 32

x = 4

We plug in x and get that:

y = 1

So in the end we get

x = 4 and y = 1
