DETAILED EXPLANATION

\n" ); document.write( "
Look at \"2%2A%28x%2B3.1%29=highlight_red%28+9.8+%29\".
Moved these terms to the left \"highlight_green%28+-9.8+%29\"
It becomes \"2%2A%28x%2B3.1%29-highlight_green%28+9.8+%29=0\".
\n" ); document.write( "
Look at \"highlight_red%28+2%2A%28x%2B3.1%29+%29-9.8=0\".
Expanded term \"2\" by using associative property on \"%28x%2B3.1%29\"
It becomes \"highlight_green%28+2%2Ax+%29%2Bhighlight_green%28+2%2A3.1+%29-9.8=0\".
\n" ); document.write( "
Look at \"2%2Ax%2Bhighlight_red%28+2%2A3.1+%29-highlight_red%28+9.8+%29=0\".
Replace constants in expression: \"highlight_red%28+2%2A3.1+%29\",\"highlight_red%28+-9.8+%29\" with \"highlight_green%28+-3.6+%29\"
It becomes \"highlight_green%28+-3.6+%29%2B2%2Ax=0\".
\n" ); document.write( "
Look at \"highlight_red%28+-3.6+%29%2B2%2Ax=0\".
Moved \"-3.6\" to the right of expression
It becomes \"2%2Ax%2Bhighlight_green%28+-3.6+%29=0\".
\n" ); document.write( "
Look at \"2%2Ax%2Bhighlight_red%28+-3.6+%29=0\".
Removed extra sign in front of \"-3.6\"
It becomes \"2%2Ax-highlight_green%28+3.6+%29=0\".
\n" ); document.write( "
Look at \"highlight_red%28+2%2Ax-3.6+%29=0\".
Solved linear equation \"highlight_red%28+2%2Ax-3.6=0+%29\" equivalent to 2*x-3.6 =0
It becomes \"highlight_green%28+0+%29=0\".
Result: \"0=0\"
\n" ); document.write( "This is an equation! Solutions: x=1.8.
