    x = 2, x = 4

    Step-by-step explanation:

    The equation y = 10 - 9x is a linear equation and the value of either y or x can be found by substituting the given values of either y or x.

    given that y = - 8, and substituting this into equation y = 10 - 9x,

    we have, - 8 = 10 - 9x

    10 + 8 = 9x

    9x = 18; dividing both sides by 9

    x = 2

    given that y = - 26, and substituting this into equation y = 10 - 9x,

    we have, - 26 = 10 - 9x

    10 + 26 = 9x

    9x = 36; dividing both sides by 9

    x = 4
