Question

find the value of p and q in equation 68+p+q=90​

Answer 1

According to the question,

68+p+q= 90

p+q=90-68

p+q= 22

p= 22-q

So, whatever the value of q be, p will be 22-q

I. e. if q= 2,

then p= 22-2 = 20

So, one of the solutions is (20,2)

Likewise you can put various values of q and to find the value of p just subtract the value of q from 22
