Question

Find the solution, given the replacement set.
5x - 2y = 6 {(-2, -8), (0, -3), (1, -1), (2, 4), (4, 7)}

Answer 1

Given the replacement set. 5x - 2y = 6 {(-2, -8), (0, -3), (1, -1), (2, 4), (4, 7)}
let(-2,-8)
=>5*(-2)-2(-8)
=>-10+16
=>6
again (0,-3)
=>5*0-2*(-3)
=>6
(1,-1)
=>5*1-2(-1)
=>5+2
=>7
(2,4)
=>5*2-2*4
=>10-8
=>2
(4,7)
=>5*4-2*7
=>20-14
=>6
hence the answer {(-2, -8), (0, -3), (4, 7)}
