Answer:

(3, 22)

Step-by-step explanation:

first you substitute 10x-8 for y in the first equation

-5x+3(10x-8)=51

then multiply

-5x+30x-24=51

add 24 to 51 and -5x to 30x

25x=75

divide by 25

x=3

then you substitute x=3 in the second equation

y=10(3)-8

30-8= 22

y=22

  15600 s/(3600 s/h) = 13/3 h = 4 1/3 h

1/3 hour is 20 minutes, so Evelyn's time of 4:16 is shorter than Andrew's time of 4:20.
