You can put this solution on YOUR website!
x+y=4----------equation(1)
\n" ); document.write( "y=2X+1 --------equation(2)
\n" ); document.write( "put the value of y in eq.(1)
\n" ); document.write( "than equation(1) becomes
\n" ); document.write( "x+2x+1=4
\n" ); document.write( "3x+1=4
\n" ); document.write( "3x=4-1
\n" ); document.write( "3x=3
\n" ); document.write( "x=3/3
\n" ); document.write( "x=1
\n" ); document.write( "put the value of x in eq.(1)
\n" ); document.write( "1+y=4
\n" ); document.write( "y=4-1
\n" ); document.write( "y=3
\n" ); document.write( "answer x=1,y=3 \n" ); document.write( "
\n" );
