Question

PLEASE HELP ME!! I’ve been working on this for an hour w/ help but still can’t get it!

Answer 1

x=2.2 y=4

Explanation:

Lets start with the first line

3y=23-5x

then you put the value of 3y into the second sentence

23-5x=15x-21

-20x=-44

x=2.2

then you put the value of x into first or second sentence to get y

5*2.2+3y=23

3y=12

y=4
