3x+2y=11...........(1)
\n" ); document.write( "7x-y=3.............(2)
\n" ); document.write( "Multiply (2) by 2 and add to (1)\r
\n" ); document.write( "\n" ); document.write( "3x+2y=11
\n" ); document.write( "14x-2y=6
\n" ); document.write( "-----------------
\n" ); document.write( "17x=17
\n" ); document.write( "Divide by 17 both sides
\n" ); document.write( "17x/17=17/17
\n" ); document.write( "x=1
\n" ); document.write( "Put the value of x in (1)
\n" ); document.write( "3x+2y=11...........(1)
\n" ); document.write( "3(1)+2y=11
\n" ); document.write( "3+2y=11
\n" ); document.write( "2y=11-3
\n" ); document.write( "2y=8
\n" ); document.write( "Divide by 2 both sides
\n" ); document.write( "2y/2=8/2
\n" ); document.write( "y=4\r
\n" ); document.write( "\n" ); document.write( "x,y=1,4\r

\n" ); document.write( "Put the values of x and y in (1)
\n" ); document.write( "3x+2y=11...........(1)
\n" ); document.write( "3(1)+2(4)=11
\n" ); document.write( "3+8=11
\n" ); document.write( "11=11
\n" ); document.write( "Put the values of x and y in (2)
\n" ); document.write( "7x-y=3.............(2)
\n" ); document.write( "7(1)-(4)=3
\n" ); document.write( "7-4=3
