......
7p + 5q = 2
8p - 9q = 17

63p + 45q = 18
40p - 45q = 85
103p = 103
p = 1
q = -1

In order to solve this system by elimination, we need to multiply these two equations by two non-zero numbers that will make one of the variables cancel out when we add the two equations together.

Since the coefficients of q are opposite in sign, it will be easier to eliminate q first. The LCM of the coefficients of q (5 and 9) i
