.
Let x = length of Tigris
then from:"length of the Euphrates River exceeds that of the Tigris by 620 miles"
x+620 = length of Euphrates
.
our equation comes from:"combined length of 2880 miles" we get
x + x+620 = 2880
2x+620 = 2880
2x = 2260
x = 1130 miles (Tigris)
.
Euphrates:
x+620 = 1130+620 = 1750 miles
