since each block is 3/8 of a mile, then how many miles in 4½? well, it'd just be their product, but let's firstly convert the mixed fraction to improper.

Rearranging the first equation:-
3x - 4y = -7
9x + 4y = 139
12x = 132
x = 132/12 = 11
Substituting fro x in the second equation:-
9(11) + 4y = 139
4y = 139 - 99 = 40
y = 40/4 = 10
Answer x = 4 , y = 10.
