Hi there,
\n" ); document.write( "Ishaan is 2 times as old as Christopher.
\n" ); document.write( "I = 2C.......(1)
\n" ); document.write( "35 years ago, Ishaan was 7 times as old as Christopher.
\n" ); document.write( "I - 35 = 7(C - 35).......(2)
\n" ); document.write( "I - 35 = 7C - 245........(2)
\n" ); document.write( "Substitute 2C for I from Eq(1) in Eq(2)
\n" ); document.write( "2C - 35 = 7C - 245
\n" ); document.write( "Collect like terms:
\n" ); document.write( "2C - 7C = -245 + 35
\n" ); document.write( "-5C = -210
\n" ); document.write( "C = 42
\n" ); document.write( "Ishaan is 84 years old
\n" ); document.write( "Christopher is 42 years old
\n" ); document.write( "Hope this helps :-)
\n" ); document.write( "
\n" );
