You can put this solution on YOUR website!
4x + y = 11......1
\n" ); document.write( "x + 2y = 8 ......2
\n" ); document.write( "..
\n" ); document.write( "Equation 2
\n" ); document.write( "x+2y=8
\n" ); document.write( "add -2y
\n" ); document.write( "x+2y-2y=8-2y
\n" ); document.write( "x= 8-2y
\n" ); document.write( "..
\n" ); document.write( "4x+y=11
\n" ); document.write( "plug the value of x in this equation
\n" ); document.write( "4(8-2y)+y= 11
\n" ); document.write( "32-8y+y=11
\n" ); document.write( "Add -32 to both sides
\n" ); document.write( "-32+32-7y=11-32
\n" ); document.write( "-7y=-21
\n" ); document.write( "y=-21/-7
\n" ); document.write( "y=3
\n" ); document.write( "..
\n" ); document.write( "plug the value of x in the equation x+2y=8
\n" ); document.write( "x+6=8
\n" ); document.write( "x=8-6=2
\n" ); document.write( "x=2
\n" ); document.write( "
\n" );
