# Math Help - Functions

1. ## Functions

I'm checking to see if I did this problem correctly.

f(x)= -3x + 7, find the value of x that leads to the given value of f(x).

:f(x)= a

a = -3x + 7

a-7/-3 = -3x/-3

x= a-7/-3 , is that right???

2. With the correct use of parenthesizes $\frac{{\left( {a - 7} \right)}}{{ - 3}}$ it is correct.
