Let
\n" ); document.write( "Present age of Moe = m years old
\n" ); document.write( "Present age of Curly = c years old\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Moe is three times older than Curly
\n" ); document.write( "m=3c..........(1)
\n" ); document.write( "Two years ago
\n" ); document.write( "Moe was = m-2 years old
\n" ); document.write( "Curly was = c-2 years old
\n" ); document.write( "Then
\n" ); document.write( "Moe was four times older than Curly was then
\n" ); document.write( "m-2=4(c-2)
\n" ); document.write( "m-2=4c-8
\n" ); document.write( "m=4c-8+2
\n" ); document.write( "m=4c-6...........(2)
\n" ); document.write( "Put the value of m from (1) to (2)
\n" ); document.write( "3c=4c-6
\n" ); document.write( "3c-4c=-6
\n" ); document.write( "-c=-6
\n" ); document.write( "Multiply by -1 both sides
\n" ); document.write( "c=6
\n" ); document.write( "Put the value of c in (1)
\n" ); document.write( "m=3c
\n" ); document.write( "m=3*6
\n" ); document.write( "m=18\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Present age of Moe = m = 18 years old
\n" ); document.write( "Present age of Curly = c = 6 years old\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
