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)

  • Algebra -

    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~ :)
