differential equations

solve the following equations
1.(x^2+1)dy/dx=4x/y

2. dy/dx=-0.7y

3.dg/dx=(4g-7)(3x+1)

Re: differential equations

Let's start with the first one...try separating the variables and integrating. What do you find?

These are all "variables separable" ... the very simplest Differential Equations.
Do you know how to solve them?
