YOUR ANSWER


  • Graphical form: f%28x%29=3x simplifies to f%28x%29-3%2Ax=0
  • Text form: f(x)=3x simplifies to f(x)-3*x=0
  • Cartoon (animation) form: simplify_cartoon%28+f%28x%29=3x+%29
    For tutors: simplify_cartoon( f(x)=3x )

DETAILED EXPLANATION

Look at f%28x%29=highlight_red%28+3%2Ax+%29.
Moved these terms to the left highlight_green%28+-3%2Ax+%29
It becomes f%28x%29-highlight_green%28+3%2Ax+%29=0.
Result: f%28x%29-3%2Ax=0
