In two barrels together 442 liters of gasoline. When 13 gasoline was taken from the first barrel

In two barrels together 442 liters of gasoline. When 13 gasoline was taken from the first barrel, and 37 gasoline was taken from the second barrel, then in both barrels of gasoline it became equal. How many liters of gasoline were in each barrel initially?

1) Let’s represent in the form x the quantity of gasoline in barrels after 13 and 37 were taken from them. Let’s make the equation:
x + 13 + x + 37 = 442
2x + 50 = 442
2x = 442-50
2x = 392
x = 392/2
x = 196
2) 196 + 13 = 209 (amount of gasoline in the first barrel)
3) 196 + 37 = 233 (amount of gasoline in the second barrel)
Answer: 209 and 233
