If you happen to form the equations the way the other person did: P + D = 25, ad P + 10D = 124, you ABSOLUTELY and UNEQUIVOCALLY DON'T need to change ANY of the 2 equations. Just SIMPLY subtract the 1st from the 2nd to get: 9D = 99, and subsequently, D, or number of dimes to be:  = 11.
\n" );
document.write( "Then, subtract 11 for 25 to get the number of pennies. That's all!!
\n" );
document.write( "No need to do any UNNECESSARY and time-consuming changes to any if the 2 equations. It's JUST SENSELSS and STUPID to do so! \n" );
document.write( "
