If there are 29 coins in all, how much money is in the coin purse? ------------ Let # of 10-peso coins be "x" ; Then # of 5-peso coins is "x-8". EQUATION: x + x-8 = 29 2x = 37 x = 37/2 -------------- Comment: That value is not possible for the number of 10-peso coins as the number must be a whole number. -------------- Check your problem statement. ============= Cheers, Stan H.
