f(x) = 3/4 * x - 7 . Find x if f(x) = - 1 . PLEASE tell how to solve it bc that what i dont know, i dont want just the answer

Eva8 [605]

Answer:

$x=-8$ if $f(x)=-1$

Step-by-step explanation:

Given --> $f(x)=-\frac{3}{4}x-7$

Substitute $f(x)=-1$ into the equation and solve for $x$ :

$-1=-\frac{3}{4}x-7$

$6=-\frac{3}{4}x$

$24=-3x$

$-8=x$

So, when $f(x)=-1,x=-8$
