4x+5y=6
\n" ); document.write( "6x-7y=-20
\n" ); document.write( "----------
\n" ); document.write( "Multiply thru 1st equation by 6
\n" ); document.write( "Multiply thru 2nd equation by 4
\n" ); document.write( "----------
\n" ); document.write( "24x + 30y = 36
\n" ); document.write( "24x - 28y = -80
\n" ); document.write( "-----
\n" ); document.write( "Subtract and solve for \"y\":
\n" ); document.write( "58y = 116
\n" ); document.write( "y = 2
\n" ); document.write( "---
\n" ); document.write( "solve for \"x\":
\n" ); document.write( "4x+5y = 6
\n" ); document.write( "4x + 5*2 = 6
\n" ); document.write( "4x = -4
\n" ); document.write( "x = -1
