Answer 1

Answer:

-5/6 =x

Step-by-step 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

Answer:

$\huge\boxed{x = -\frac{5}{6}}$

Step-by-step 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

$x = - \frac{10}{12}$

$x = -\frac{5}{6}$
