Yes D=M/V is used in chemistry.
D stands for density.
M stands for mass
V stands for volume

<h3>What is a linear equation in two variables ?</h3>
An equation is linear if has highest degree of 1 and it has two variables.Generally they are in x and y.
For example -: 2x + 3y = 10
According to the given question a farmer has some hens and goats. He counts a total of 60 eyes and 86 feet between them.
Let us denote Hens by H and Goats by G.
We know both of them has 2 eyes each and we also know that a Hen has 2 legs and a Goat has 4 legs.
There fore the given data we can form two equations.
2H + 2G = 60 and 2H + 4G = 86.
Solving these two equations we have G = 13 and H = 17.
