DETAILED EXPLANATION

Look at 2%2Ax-8=highlight_red%28+x+%29.
Moved these terms to the left highlight_green%28+-x+%29
It becomes 2%2Ax-8-highlight_green%28+x+%29=0.
Look at 2%2Ax-highlight_red%28+8+%29-x=0.
Moved -8 to the right of expression
It becomes 2%2Ax-x-highlight_green%28+8+%29=0.
Look at highlight_red%28+2%2Ax+%29-highlight_red%28+x+%29-8=0.
Eliminated similar terms highlight_red%28+2%2Ax+%29,highlight_red%28+-x+%29 replacing them with highlight_green%28+%282-1%29%2Ax+%29
It becomes highlight_green%28+%282-1%29%2Ax+%29-8=0.
Look at highlight_red%28+%282-1%29+%29%2Ax-8=0.
Remove extraneous '1' from product highlight_red%28+%282-1%29+%29
It becomes x-8=0.
Look at highlight_red%28+x-8+%29=0.
Solved linear equation highlight_red%28+x-8=0+%29 equivalent to x-8 =0
It becomes highlight_green%28+0+%29=0.
Result: 0=0
This is an equation! Solutions: x=8.
