x+y=10
\n" ); document.write( "x=10-y..........(1)\r
\n" ); document.write( "\n" ); document.write( "x^2+y^2=58......(2)\r
\n" ); document.write( "\n" ); document.write( "Put the value of x in equation (2)
\n" ); document.write( "(10-y)^2+Y^2=58\r
\n" ); document.write( "\n" ); document.write( "100-20y+y^2+y^2=58
\n" ); document.write( "100-20y+2y^2=58
\n" ); document.write( "Divide by 2 both sides of the equation
\n" ); document.write( "50-10y+y^2=29
\n" ); document.write( "y^2-10y+50-29=0
\n" ); document.write( "Y^2-10y+21=0
\n" ); document.write( "y^2-7y-3y+21=0
\n" ); document.write( "y(y-7)-3(y-7)=0
\n" ); document.write( "(y-7)(y-3)=0
\n" ); document.write( "y-7=0 or y-3=0
\n" ); document.write( "y=7 or y=3\r
\n" ); document.write( "\n" ); document.write( "Put the values of y in equation (1)
\n" ); document.write( "when y=7
\n" ); document.write( "x=10-7
\n" ); document.write( "x=3
\n" ); document.write( "When y=3
\n" ); document.write( "x=10-3
\n" ); document.write( "x=7\r
\n" ); document.write( "\n" ); document.write( "So two numbers are 7,3
