8y + 7x = 25
(b) Find three solutions of the equation.
(2, 39/8), (4, 53/8), (6, 67/8)
(2, 11/8), (4, 53/8), (6, 67/8)
(2, 39/8), (4, 53/8), (6, 67/8)
(2, 39/8), (4, 53/8), (6, 34/25)

at x = 2
8y + 7*2 = 25
8y = 25  14
y = 39/8
at x = 4
8y + 7*4 = 25
8y = 25  28
y = 53/8
at x = 6
8y + 7*6 = 25
8y = 25  42
y = 67/8
thus it's
(2, 39/8), (4, 53/8), (6, 67/8)
hope this helps~ :)
