Introduction

An equation is basically the mathematical manner to portray a relationship among two variables
The variables may be physical quantities, possibly temperature and position for instance, in
which case the equation informs us how one quantity relies on the other, so how the temperature
differs with position. The easiest type of relationship that two such variables can comprise
a linear relationship. This shows that to locate one quantity from the other you multiply the
first by some number, then add a different number to the outcome. In this unit, you will
a the con of linear equations and equations reducible to linear form.

Solution
in which P & Q are functions of x alone or constant is called a linear equation of the first order
Given equation is
d 1+ 1+r

The general solution of the above equation can be found as follows
