at the town waterworks,2 large pumps and 4 smaller ones delivered 4,800 gallons of water a minute.each of the large pumps delivered 4 times as much water as each small pump.how many gallons per minute did each pump deliver?

small pump : x g/m
large pump : 4x g/m
looks like we solving
2(4x) + 4x = 4800
