Answer:

x=2; y=1

Step-by-step explanation:

Since the triangle is equilateral, which means three sides have the same length.

So we have：4x-y=2x+3y=7

$4x-y=2x+3y\\4x-y+y=2x+3y+y\\4x=2x+4y\\2x=4y\\x=2y\\$

Since 2x+3y=7 and plug in x=2y

we have

$2x+3y=7\\2(2y)+3y=7\\4y+3y=7\\7y=7\\y=1$

and since y=1

x=2
