John is shipping a box. FedEx is going to charge him a flat rate of $5 and then $0.50 per pound. UPS is going to charge him $2 per pound. He wants to find the cheaper carrier and writes his system of equations as follows: Y = .50x + 5 Y = 2x Did John write his systems of equations correctly?

Yes, John did write his systems of equations correctly.

Step-by-step explanation:

FedEx charges him a flat rate of $5, so the 5 stands alone in the problem, and $0.50 per pound, so the 0.5 stands with the x because it represents each pound.

UPS doesn't charge him a flat rate so there is no stand-alone number. Since they charge $2 per pound, 2 is with the x, again representing each pound.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

x=6 and x=3
