Let
\n" ); document.write( "x be the smaller and y be the larger number
\n" ); document.write( "The sum of two numbers is 90
\n" ); document.write( "x+y=90
\n" ); document.write( "x=90-y...........(1)
\n" ); document.write( "Three times the smaller is 10 more than the larger.
\n" ); document.write( "3x=y+10..........(2)
\n" ); document.write( "Substitute the value of x from (1) to (2)
\n" ); document.write( "3(90-y)=y+10..........(2)
\n" ); document.write( "270-3y=y+10
\n" ); document.write( "-3y-y=10-270
\n" ); document.write( "-4y=-260
\n" ); document.write( "-4y/-4=-260/-4
\n" ); document.write( "y=65
\n" ); document.write( "Put the value of y in (1)
\n" ); document.write( "x=90-y...........(1)
\n" ); document.write( "x=90-65
\n" ); document.write( "x=25\r
\n" ); document.write( "\n" ); document.write( "Smaller number x = 25
\n" ); document.write( "Larger number y = 65
\n" ); document.write( " \n" ); document.write( "
\n" );
