Exercise

$\left(4y-3x\right)dx+5xdy=0$

Step-by-step Solution

1

We can identify that the differential equation $\left(4y-3x\right)dx+5x\cdot dy=0$ is homogeneous, since it is written in the standard form $M(x,y)dx+N(x,y)dy=0$, where $M(x,y)$ and $N(x,y)$ are the partial derivatives of a two-variable function $f(x,y)$ and both are homogeneous functions of the same degree

$\left(4y-3x\right)dx+5x\cdot dy=0$
2

Use the substitution: $y=ux$

$\left(4ux-3x\right)dx+5x\left(u\cdot dx+x\cdot du\right)=0$
3

Expand and simplify

$\frac{5}{-3u+1}du=\frac{3}{x}dx$
4

Integrate both sides of the differential equation, the left side with respect to $u$, and the right side with respect to $x$

$\int\frac{5}{-3u+1}du=\int\frac{3}{x}dx$
5

Solve the integral $\int\frac{5}{-3u+1}du$ and replace the result in the differential equation

$\frac{5}{-3}\ln\left|-3u+1\right|=\int\frac{3}{x}dx$
6

Solve the integral $\int\frac{3}{x}dx$ and replace the result in the differential equation

$\frac{5}{-3}\ln\left|-3u+1\right|=3\ln\left|x\right|+C_0$
7

Replace $u$ with the value $\frac{y}{x}$

$\frac{5}{-3}\ln\left(-3\left(\frac{y}{x}\right)+1\right)=3\ln\left(x\right)+C_0$
8

Multiplying the fraction by $-3$

$\frac{5}{-3}\ln\left|\frac{-3y}{x}+1\right|=3\ln\left|x\right|+C_0$

Final answer to the exercise

$\frac{5}{-3}\ln\left|\frac{-3y}{x}+1\right|=3\ln\left|x\right|+C_0$
