Five years ago I was 5 times older than my son. In 8 years’ time
\n" ); document.write( "I will be 3 times older than my son. How old am I today?\r
\n" ); document.write( "\n" ); document.write( "I know it will be a simultaneous equation, but I'm struggling to understand the two equations. So far I've done x-5=5(y-5)
\n" ); document.write( " x+8=3(y+8)
\n" ); document.write( "Now I'm not sure what to do.
\n" ); document.write( "-----------
\n" ); document.write( "You made the 2 eqns, that's where most people have problems.
\n" ); document.write( "x-5=5(y-5)
\n" ); document.write( "x+8=3(y+8)
\n" ); document.write( "-----
\n" ); document.write( "x - 5 = 5y - 25
\n" ); document.write( "x + 8 = 3y + 24
\n" ); document.write( "------------------ Subtract
\n" ); document.write( "-13 = 2y - 49
\n" ); document.write( "2y = 36
\n" ); document.write( "y = 18
\n" ); document.write( "-------
\n" ); document.write( "x = 70
\n" ); document.write( "
\n" );
