The Missouri River is 149 miles longer than double the Snake River. The Potomac River is 796 miles shorter than the Snake River. The combined lengths of these 3 rivers is 3,685 miles. Find the length of each.
snake river length be x miles
missouri river length will be x+149
Potomac river length = x-796
x+x+149+x-796=3685
3x= 3685=796-149
3x=4332
x=1444 miles length of snake river
1444+149= 1593 length of missouri river
Potomac river will be 1444-796=1648 miles
