You can put this solution on YOUR website!
set it up like this\r
\n" ); document.write( "\n" ); document.write( "4m = f
\n" ); document.write( "2m + 20 = f\r
\n" ); document.write( "\n" ); document.write( "Multiply the top equation by -1 to eliminate to f(represents father's age)\r
\n" ); document.write( "\n" ); document.write( "-4m = -f
\n" ); document.write( "2m + 20 = f\r
\n" ); document.write( "\n" ); document.write( "Add equations together\r
\n" ); document.write( "\n" ); document.write( "-2m + 20 = 0
\n" ); document.write( "-2m = -20\r
\n" ); document.write( "\n" ); document.write( "m = 10\r
\n" ); document.write( "\n" ); document.write( "You are 10 years old.
\n" ); document.write( "Your father is 40 years old.\r
