Answer:

x=2, y=3

Explanation:

This is a system of equations.

To solve a system of equations, we use the substitution method.

We can plug in the first equation,
x=2y-4, into the value for x in the second equation. Now, the second equation looks like this:


2*(2y-4)+y=7

We simplify and solve for y:


4y-8+y=7


5y=15


y=3

Now, we plug in the value for y, which is 3, into either equation. I will just use the first equation:


x=2*3-4


x = 2

Let me know if my explanation is unclear.
