An independent system has different slopes hence has a unique solution.
If two lines have the same slope then, they are inconsistent. The reason is that the two lines could have NO SOLUTION or INFINITELY MANY SOLUTION.
An inconsistent system that have infinitely many solution is said to be dependent.
Now let us make the subject in both equations, to obtain,
For the seccond equation, we have
Wow, the two systems have the same slope and intercept. This means the system has infinitely many solution, hence it is dependent.
<h2>The two systems are dependent</h2>
Let
x---------> the rate of the boat in still water in mph
y--------> the rate of the current in mph
we know that
Upstream
equation
Downstream
equation
Adds equation and equation
Find the value of y
therefore
the answer is
the rate of the boat in still water is
the rate of the current is
