Answer 1

-5/6 =x

Explanation:

f(x) = -12x+7

We want to find x when f(x) = 17

17 = -12x+7

Subtract 7 from each side

17-7 = -12x +7-7

10 = -12x

Divide each side by 12

10/-12 = -12x/-12

-5/6 =x

Answer 2

`\huge\boxed{x = -(5)/(6)}`

Explanation:

`f(x) = -12x+7`

Given that f(x) = 17

`17 = -12x+7`

Subtracting 7 to both sides

`17-7 = -12x`

10 = -12 x

Dividing both sides by 12

`x = - (10)/(12)`

`x = -(5)/(6)`
