2/3x+3/5y=-17
\n" ); document.write( "1/2x-1/3y=-1
\n" ); document.write( "==============
\n" ); document.write( "Multiply thru 1st by 15.
\n" ); document.write( "Multiply thru 2nd by 6.
\n" ); document.write( "--------------
\n" ); document.write( "10x + 9y = -15*17
\n" ); document.write( "3x - 2y = -6
\n" ); document.write( "---
\n" ); document.write( "Multiply thru 1st by 3
\n" ); document.write( "Multiply thru 2nd by 10
\n" ); document.write( "-----
\n" ); document.write( "30x + 27y = -45*17
\n" ); document.write( "30x - 20y = -60
\n" ); document.write( "-----------------------
\n" ); document.write( "Subtract and solve for \"y\":
\n" ); document.write( "47y = -705
\n" ); document.write( "y = -15
\n" ); document.write( "---
\n" ); document.write( "Solve for \"x\":
\n" ); document.write( "3x-2y = -6
\n" ); document.write( "3x+30 = -6
\n" ); document.write( "3x = -36
\n" ); document.write( "x = -12
