DETAILED EXPLANATION

Look at highlight_red%28+x%2F7+%29-highlight_red%28+x%2F9+%29=2.
Eliminated similar terms highlight_red%28+x%2F7+%29,highlight_red%28+-x%2F9+%29 replacing them with highlight_green%28+%281%2F7-1%2F9%29%2Ax+%29
It becomes highlight_green%28+%281%2F7-1%2F9%29%2Ax+%29=2.
Look at %28highlight_red%28+1%2F7+%29-highlight_red%28+1%2F9+%29%29%2Ax=2.
Added fractions or integers together
It becomes %28highlight_green%28+2%2F63+%29%29%2Ax=2.
Look at highlight_red%28+%28highlight_red%28+2%2F63+%29%29%2Ax+%29=2.
Remove unneeded parentheses around factor highlight_red%28+2+%29,highlight_red%28+1%2F63+%29
It becomes highlight_green%28+2+%29%2Fhighlight_green%28+63+%29%2Ax=2.
Look at 2%2F63%2Ax=highlight_red%28+2+%29.
Moved these terms to the left highlight_green%28+-2+%29
It becomes 2%2F63%2Ax-highlight_green%28+2+%29=0.
Look at highlight_red%28+2%2F63%2Ax-2+%29=0.
Solved linear equation highlight_red%28+2%2F63%2Ax-2=0+%29 equivalent to 0.0317460317460317*x-2 =0
It becomes highlight_green%28+0+%29=0.
Result: 0=0
This is an equation! Solutions: x=63.
