When we identify that a differential equation has an expression of the form $Ax+By+C$, we can apply a linear substitution in order to simplify it to a separable equation. We can identify that $x+y$ has the form $Ax+By+C$. Let's define a new variable $u$ and set it equal to the expression

$u=x+y$

Learn how to solve differential equations problems step by step online. Solve the differential equation dy/dx=sin(x+y)^2. When we identify that a differential equation has an expression of the form Ax+By+C, we can apply a linear substitution in order to simplify it to a separable equation. We can identify that x+y has the form Ax+By+C. Let's define a new variable u and set it equal to the expression. Isolate the dependent variable y. Differentiate both sides of the equation with respect to the independent variable x. Now, substitute x+y and \frac{dy}{dx} on the original differential equation. We will see that it results in a separable equation that we can easily solve.
