Step-by-step explanation:
We are told that the boat can travel 25 miles upstream in 5 hours. That comes to
25 miles
------------ = 5 mph.
5 hours
In the same 5 hours, that boat can travel 50 miles downstream. That comes to
50 miles
------------ = 10 mph
5 hours
Was there more to this question than the above?
Note: "It can go 50 miles downstream IN the same time (5 hours)."

Answer:
x = -2, y=1
Step-by-step explanation:
x-7y=-9---------------------equation 1
-x+8y=10-------------------equation 2
From equation 1, make x the subject of formula
x=7y-9----------------------equation 3
substituting x=7y-9 in equation 2,
-(7y-9)+8y=10
Expanding bracket
-7y+9+8y=10
Collecting like terms
8y-7y=10-9
y=1
substituting y=1 in 3
x=7(1)-9
x=7-9
x=-2
