Let two numbers be 'x' and 'y'
\n" ); document.write( "Given:Sum of the numbers, x+y=45 .....(1)
\n" ); document.write( "Difference of the numbers,x-y=11 .....(2)
\n" ); document.write( "We have to cancel any one variable, if we add the equations'y' will get cancelled
\n" ); document.write( " x+y=45
\n" ); document.write( " x-y=11
\n" ); document.write( "2x=56
\n" ); document.write( " x=56/2
\n" ); document.write( " x=28 ...(3)
\n" ); document.write( "Substitute the value of x in say equation 1
\n" ); document.write( " x+y=45
\n" ); document.write( "28+y=45
\n" ); document.write( " y=45-28
\n" ); document.write( " y=17
\n" ); document.write( "
\n" ); document.write( " \n" ); document.write( "
