x + --(y(x)) = 2
dx
$$x + \frac{d}{d x} y{\left(x \right)} = 2$$
x + y' = 2
Detail solution
Given the equation:
y' = $$2 - x$$
This differential equation has the form:
It is solved by multiplying both sides of the equation by dx:
And by using the integrals of the both equation sides:
or
In this case,
f(x) = $$2 - x$$
Consequently, the solution will be
y = $$\int \left(2 - x\right)\, dx$$
Detailed solution of the integral
or
y = $$- \frac{x^{2}}{2} + 2 x$$ + C1
where C1 is constant, independent of x
y' = $$2 - x$$
This differential equation has the form:
y' = f(x)
It is solved by multiplying both sides of the equation by dx:
y'dx = f(x)dx, or
d(y) = f(x)dx
And by using the integrals of the both equation sides:
∫ d(y) = ∫ f(x) dx
or
y = ∫ f(x) dx
In this case,
f(x) = $$2 - x$$
Consequently, the solution will be
y = $$\int \left(2 - x\right)\, dx$$
Detailed solution of the integral
or
y = $$- \frac{x^{2}}{2} + 2 x$$ + C1
where C1 is constant, independent of x
