The value of y, when x = 3, would be 9.

HERE'S HOW I GOT THAT ANSWER:
When you multiply 6.4 and 3, your would get 19.2. So you would subtract 44.4 and 19.2, and then you would get 25.2. Once you would get that, you would divide 25.2 by 2.8 so you could isolate the y, and once you did that, you would get 9.

6.4(3) + 2.8y = 44.4       
19.2 + 2.8y = 44.4 
2.8y = 25.2
y = 9
