4x+3y=26..........(1)
\n" ); document.write( "y=3x..............(2)\r
\n" ); document.write( "\n" ); document.write( "Substitute the value of y from (2) to (1)\r
\n" ); document.write( "\n" ); document.write( "4x+3(3x)=26
\n" ); document.write( "4x+9x=26
\n" ); document.write( "13x=26
\n" ); document.write( "Divide both sides of above equation by 13\r
\n" ); document.write( "\n" ); document.write( "13x/13=26/13
\n" ); document.write( "x=2\r
\n" ); document.write( "\n" ); document.write( "Now substitute the value of x in (2)
\n" ); document.write( "y=3x
\n" ); document.write( "y=3(2)
\n" ); document.write( "y=6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(x,y)=(2,6)\r

\n" ); document.write( "======
\n" ); document.write( "Put the value of x and y in (1)
\n" ); document.write( "4x+3y=26..........(1)
\n" ); document.write( "4(2)+3(6)=26
\n" ); document.write( "8+18=26
\n" ); document.write( "26=26\r
