x+4y=14 ..........(1)
\n" ); document.write( "x+3y=11 ..........(2)\r
\n" ); document.write( "\n" ); document.write( "Subtract (2) from (1)
\n" ); document.write( "x+4y=14
\n" ); document.write( "-x-3y=-11
\n" ); document.write( "--------------
\n" ); document.write( "y=3\r
\n" ); document.write( "\n" ); document.write( "Plug in the value of y in (1)\r
\n" ); document.write( "\n" ); document.write( "x+4y=14
\n" ); document.write( "x+4(3)=14
\n" ); document.write( "x+12=14
\n" ); document.write( "Subtract 12 from both sides
\n" ); document.write( "x+12-12=14-12
\n" ); document.write( "Cancel out 12 from Left Hand Side (LHS)
\n" ); document.write( "x=2\r
\n" ); document.write( "\n" ); document.write( "x,y = 2, 3\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check
\n" ); document.write( "======
\n" ); document.write( "Plug in the values of x and y in (1)\r
\n" ); document.write( "\n" ); document.write( "x+4y=14 ..........(1)
\n" ); document.write( "2+4(3)=14
\n" ); document.write( "2+12=14
\n" ); document.write( "14=14\r
\n" ); document.write( "\n" ); document.write( "Now
\n" ); document.write( "Plug in the values of x and y in (2)\r
\n" ); document.write( "\n" ); document.write( "x+3y=11 ..........(2)
\n" ); document.write( "2+3(3)=11
\n" ); document.write( "2+9=11
\n" ); document.write( "11=11
\n" ); document.write( " \n" ); document.write( "
\n" );
