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.
