Question

What is the ordered pairs that satisfy the equation 6x−1y=21?

Answer 1

Solution:

Given equation:

6x-y=21

=> 6x-21 = y

=> y = 6x-21

i) If x = 0 then

y = 6×0-21 = -21

(x,y) = (0,-21)

ii) If x = 2 ,then

y = 6×2-21

=> y = 12 -21 = -9

(x,y) = (2,-9)

Therefore,

Required ordered pairs are

(0,-21),(2,-9)
