Someone solve this for me please

Mathematics
1 answer:
Butoxors [25]2 years ago
5 0

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
