Answer:

y=[tex]\frac{x}{5}[/tex]+3

Step-by-step explanation:

1. Replace f(x) to x and replace x with y.

     x=5y-15

2. Then, add 15 to both sides

x+15=5y-15+15

5y=x+15

3. Divide both sides by 5

[tex]\frac{5y}{5}[/tex]=[tex]\frac{x}{5}[/tex]+[tex]\frac{15}{5}[/tex]

y=[tex]\frac{x}{5}[/tex]+3

4. Enjoy your answer.
