  • (5x - 1)/(x + 2) ≥ 1
    (5x-1)/(x+2) - 1 ≥ 0
    (5x-1)/(x+2) - (x+2)/(x+2) ≥ 0
    (5x - 1 - (x + 2)) / (x + 2) ≥ 0
    (5x - 1 - x - 2) / (x + 2) ≥ 0
    (4x - 3) / (x + 2) ≥ 0
    buat garis bilangan di
    4x - 3 = 0
    4x = 3
    x = ¾
    x + 2 = 0
    x = -2
    + + + + - - - - - - + + +
    ---------•---------•----------
    ````````` -2 ```````` ¾
    x ≤ -2 atau x ≥ ¾
    syarat x + 2 ≠ 0
    x ≠ -2

    maka hp x < -2 atau x ≥ ¾
