As we already have the value of y,we can put it into another equation.
Here's how we can solve the equation:
y = 2x+48...(1)
y = 8x...(2)
Put (2) into (1)
(8x) = 2x+48
8x-2x = 48
6x = 48
x = 8...(3)
Put (3) into (1)
y = 8(8)
y = 64
Thus, x=8, y+64

For first 50 miles:-
x + 9 = 50 / t where x is average speed for the last 68 miles and t = time taken for the first 50 miles.
For the second 68 miles:-
x = 68 / (3 - t)
Substitute for x in first equation:-
68 / (3 - t) + 9 = 50/t
68t + 9t(3 - t) = 50(3 - t)
68t + 27t - 9t^2 = 150 - 50t
9t^2 - 145t + 150 = 0
t = 1.111 , 15 (ignore the 15 hours as total time = 3).
so the speed for the first 50 miles = 50 / 1.111 = 45 miles per hour Answer
