$u=x-y-1$
Learn how to solve problems step by step online. Solve the differential equation dx/dy=sin(x-y+-1). 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-1 has the form Ax+By+C. Let's define a new variable u and set it equal to the expression. Isolate the dependent variable x. Differentiate both sides of the equation with respect to the independent variable y. Now, substitute x-y-1 and \frac{dx}{dy} on the original differential equation. We will see that it results in a separable equation that we can easily solve.
