Mathematics Class 10. Part 1- Linear Equation Introduction

Chapter 1: LINEAR EQUATIONS IN TWO VARIABLE

• Defn: An equation which contains two variables and the degree of each term containing variable is one, is called a linear equation in two variable.

Ex: 2x+3y=10,  x+y=8

• General form of a linear equation in two variable is ax+by+c=0,

where a,b,c are real numbers and a, b are not equal to zero at the same time.
and x,y are variables

Ex. Consider the equation 7x-3=4y
 We can write the above equation as 7x-4y=3 (general form)

Examples of linear eqation in two variable

1)4m+3n=12
2)4/x + 5/y =16
