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???

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