x - boat speed; y - current speed; Path = 336:2 = 168 miles
1) 12 * (x + y) = 168; -> x + y = 14;
2) 14 * (x - y) = 168; -> x - y = 12;
1) x = 14 - y;
2) (14 - y) - y = 12;
14 - 2y = 12;
2y = 2;
y = 1 mph
x = 14 - 1 = 13 mph
Answer:
Boat speed = 13 mph
Current speed = 1 mph
Answer:
none
Step-by-step explanation:
Because X has the same coefficient on both sides but a different value is being added to it, there cannot be an solution.
9x+3=9x+5
-9x -5
-2=0, which doesnt work so theres no solution
Answer:
12
