RD Sharma Solutions for Class 10 Maths Chapter 3 Pair of Linear Equations in Two Variables

RD Sharma Solutions for Class 10 Chapter 3 “Pair of Linear Equation in Two Variable”- An equation in the form of ax+by+c, where a,b and c are real numbers and a,b are not equal to zero, is called a linear equation in two variables. Linear equations in two variables, explain the geometry of lines or the graph of two lines, plotted to solve the given equations. An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e. a and b respectively, are not equal to zero. Let’s see some of the concepts discussed in this chapter:

  • Systems of linear equations in two variables
  • The solution of a system of linear equations in two variables
  • Graphical and algebraic methods of solving a system of linear equations in two variables like substitution, elimination, and cross-multiplication methods.
  • Consistent and inconsistent system of equations.
  • Applications of linear equations in two variables in solving simple problems from different areas.
