Answer:
Step-by-step explanation:
Let x = the current of the river
Then 21 + x = the speed going downstream (with the current)
a nd 21 - x = the speed going upstream (against the current)
Distance = speed × time
d = st
t = d/s
Time going downstream = time going upstream

Answer:
A = 1/2
Step-by-step explanation:
"A+6=9-5A" is already an equation, and your task here is to solve it for A.
Adding 5A to both sides results in
A + 5A + 6 = 9, or
6A + 6 = 9.
Subtracting 6 from both sides results in
6A = 3.
Thus, A = 3/6, or, in simplest terms, A = 1/2.
