Y has a coefficient of 1 in the first equation, so it is easiest to use that one to write an expression for y.
... y = 20 - 2x . . . . . subtract 2x
Now, this expression can be substituted for y in the second equation.
Then, using the expression for y, we find its value
... y = 20 -2·7 = 6
The solution of the equations is (x, y) = (7, 6).
The given pair of functions is
The derivatives are
The Wronskian is
Answer:
To get the answer we have to substitute x=3 and add 6 to the result.
Lets do this
f(x)=7-2x
f(3)=7-2*3=7-6=1
f(3)+6=1+6=7 - its the result
Answer:
Rational
