DETAILED EXPLANATION

Look at 3%2Ag%2B9=highlight_red%28+15%2Ag-9+%29.
Moved these terms to the left highlight_green%28+-15%2Ag+%29,highlight_green%28+9+%29
It becomes 3%2Ag%2B9-highlight_green%28+15%2Ag+%29%2Bhighlight_green%28+9+%29=0.
Look at 3%2Ag%2Bhighlight_red%28+9+%29-15%2Ag%2Bhighlight_red%28+9+%29=0.
Added fractions or integers together
It becomes 3%2Ag%2Bhighlight_green%28+18+%29-15%2Ag=0.
Look at 3%2Ag%2Bhighlight_red%28+18+%29-15%2Ag=0.
Moved 18 to the right of expression
It becomes 3%2Ag-15%2Ag%2Bhighlight_green%28+18+%29=0.
Look at highlight_red%28+3%2Ag+%29-highlight_red%28+15%2Ag+%29%2B18=0.
Eliminated similar terms highlight_red%28+3%2Ag+%29,highlight_red%28+-15%2Ag+%29 replacing them with highlight_green%28+%283-15%29%2Ag+%29
It becomes highlight_green%28+%283-15%29%2Ag+%29%2B18=0.
Look at %28highlight_red%28+3+%29-highlight_red%28+15+%29%29%2Ag%2B18=0.
Added fractions or integers together
It becomes %28highlight_green%28+-12+%29%29%2Ag%2B18=0.
Look at %28highlight_red%28+-12+%29%29%2Ag%2B18=0.
Removed extra sign in front of -12
It becomes %28-highlight_green%28+12+%29%29%2Ag%2B18=0.
Look at highlight_red%28+%28-highlight_red%28+12+%29%29%2Ag+%29%2B18=0.
Remove unneeded parentheses around factor highlight_red%28+12+%29
It becomes -highlight_green%28+12+%29%2Ag%2B18=0.
Look at highlight_red%28+-12%2Ag%2B18+%29=0.
Solved linear equation highlight_red%28+-12%2Ag%2B18=0+%29 equivalent to -12*g+18 =0
It becomes highlight_green%28+0+%29=0.
Result: 0=0
