DETAILED EXPLANATION

\n" ); document.write( "
Look at .
Eliminated similar terms \"highlight_red%28+x+%29\",\"highlight_red%28+x+%29\",\"highlight_red%28+-x+%29\",\"highlight_red%28+2%2Ax+%29\" replacing them with \"highlight_green%28+%281%2B1-1%2B2%29%2Ax+%29\"
It becomes \"highlight_green%28+%281%2B1-1%2B2%29%2Ax+%29=6\".
\n" ); document.write( "
Look at .
Added fractions or integers together
It becomes \"%28highlight_green%28+3+%29%29%2Ax=6\".
\n" ); document.write( "
Look at \"highlight_red%28+%28highlight_red%28+3+%29%29%2Ax+%29=6\".
Remove unneeded parentheses around factor \"highlight_red%28+3+%29\"
It becomes \"highlight_green%28+3+%29%2Ax=6\".
\n" ); document.write( "
Look at \"3%2Ax=highlight_red%28+6+%29\".
Moved these terms to the left \"highlight_green%28+-6+%29\"
It becomes \"3%2Ax-highlight_green%28+6+%29=0\".
\n" ); document.write( "
Look at \"highlight_red%28+3%2Ax-6+%29=0\".
Solved linear equation \"highlight_red%28+3%2Ax-6=0+%29\" equivalent to 3*x-6 =0
It becomes \"highlight_green%28+0+%29=0\".
Result: \"0=0\"

Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation \"4+x+%2B+2+y+=+8\" describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is \"-a%2Fb+=+-4%2F2\".
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 8/4 = 2.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 8/2 = 4.
  • Slope is -4/2 = -2.
  • Equation in slope-intercept form: y=-2*x+4.

DETAILED EXPLANATION

\n" ); document.write( "
Look at \"highlight_red%28+x+%29%5E2-2%2Ax\".
Replaced x with 3
It becomes \"highlight_green%28+3+%29%5E2-2%2Ax\".
\n" ); document.write( "
Look at \"highlight_red%28+3+%29%5Ehighlight_red%28+2+%29-2%2Ax\".
Replace constants in factor: \"highlight_red%28+3+%29\",\"highlight_red%28+2+%29\" with \"highlight_green%28+9+%29\"
It becomes \"highlight_green%28+9+%29-2%2Ax\".
\n" ); document.write( "
Look at \"9-2%2Ahighlight_red%28+x+%29\".
Replaced x with 3
It becomes \"9-2%2Ahighlight_green%28+3+%29\".
\n" ); document.write( "
Look at \"highlight_red%28+9+%29-highlight_red%28+2%2A3+%29\".
Replace constants in expression: \"highlight_red%28+9+%29\",\"highlight_red%28+-2%2A3+%29\" with \"highlight_green%28+3+%29\"
It becomes \"highlight_green%28+3+%29\".
