3x-4y=1
\n" ); document.write( "2x-5y=3
\n" ); document.write( "---------
\n" ); document.write( "Multiply thru 1st by 2 ; Multiply thru 2nd by 3:
\n" ); document.write( "---------
\n" ); document.write( "6x - 8y = 2
\n" ); document.write( "6x -15y = 9
\n" ); document.write( "--------------
\n" ); document.write( "Subtract 2nd from 1st:
\n" ); document.write( "7y = -7
\n" ); document.write( "y = -1
\n" ); document.write( "--------
\n" ); document.write( "Substitute into 2x-5y=3 to solve for \"x\":
\n" ); document.write( "2x -5*-1 = 3
\n" ); document.write( "2x = -2
\n" ); document.write( "x = -1
\n" ); document.write( "-------------
\n" ); document.write( "Solution: (-1,-1)
