DETAILED EXPLANATION

Look at 6=highlight_red%28+-9%2Ax-3%2F4+%29.
Moved these terms to the left highlight_green%28+9%2Ax+%29,highlight_green%28+3%2F4+%29
It becomes 6%2Bhighlight_green%28+9%2Ax+%29%2Bhighlight_green%28+3%2F4+%29=0.
Look at highlight_red%28+6+%29%2B9%2Ax%2Bhighlight_red%28+3%2F4+%29=0.
Added fractions or integers together
It becomes highlight_green%28+27%2F4+%29%2B9%2Ax=0.
Look at highlight_red%28+27%2F4+%29%2B9%2Ax=0.
Moved 27%2F4 to the right of expression
It becomes 9%2Ax%2Bhighlight_green%28+27%2F4+%29=0.
Look at highlight_red%28+9%2Ax%2B27%2F4+%29=0.
Solved linear equation highlight_red%28+9%2Ax%2B27%2F4=0+%29 equivalent to 9*x+6.75 =0
It becomes highlight_green%28+0+%29=0.
Result: 0=0
This is an equation! Solutions: x=-0.75.
