The equation of a function is y = 10 - 9x. Find the value of x when

y = - 8,

y = - 26

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
