RD Sharma Class 10 Chapter 3 (Pair of Linear Equations in Two Variables) Solutions

RD Sharma Class 10 Chapter-3 contain extra questions in addition to those of NCERT Class 10 textbook. Initially, you will learn to represent and solve a pair of linear equations using substitution, elimination or cross-multiplication method. Next, you will study how to represent a pair of linear equations in both graphical and algebraic method. 

You need to follow the similar pattern of study that you followed for NCERT when solving textbook questions of RD Sharma Class 10 Chapter-3. Now, validate your answers by taking reference from solutions given below.

Important Formulas| RD Sharma Class 10 Chapter-3

1. Two linear equations having two similar variables can be expressed in the general form shown below. 

a₁x + b₁y + c₁ = 0

a₂x + b₂y + c₂ = 0

2. Consider the two equations mentioned above while finding the value of variables. You shall come across the following situations. 

a). a₁/a₂ ≠ b₁/b₂ (In case of consistent pair of linear equations)

b). a₁/a₂ = b₁/b₂ ≠ c₁/c₂ (In case of inconsistent pair of linear equations)

c). a₁/a₂ = b₁/b₂ = c₁/c₂ (This condition arises when the pair of linear equations is consistent and dependent)
