Leonard weighed four phones and two chargers and found out that they weighed 46 ounces. Hratch weighed 3 phones and three chargers and found out thatchy weighed 36 ounces. Find the weight of one of each object.
4p + 2c = 46 or 2p + c = 23
3p + 3c = 36 or p + c = 12
just subtract them and you have p
then sub that back into p + c = 12 to find c
