Get NCERT solutions of Chapter 3 Class 10 - Pair of Linear Equations in Two Variables at Teachoo. Answers to all exercise questions, examples and optional questions have been provided with video of each and every question

We studied Linear Equations in Two Variables in Class 9, we will study **pair of** linear equations in this chapter.

In this chapter, we will learn

- What are
**Linear Equations in Two Variables** - Converting
**statements into Equations**, and**drawing graph**of those linear equations **Possible Type of Graphs**for Pair of Linear Equations in Two Variables - Two Lines Intersecting, Two lines Parallel, Coincident Lines- Finding s
**olution of equations from graphs** **Consistency**of equations by finding**ratio of a**_{1}/a_{2}, b_{1}/b_{2}, c_{1}/c_{2}- and checking whether lines are

**Intersecting Lines**(Exactly one solution - unique)**Coincident Lines**(Infinitely many solutions)**Parallel Lines (**No solutions)

- Solving Pair of Linear Equations by
**Substitution**Method**Elimination**Method**Cross Multiplication**Method

- Solving
**complicated equations**like 2/x + 3/y = 4**by substituting variables**(like putting p = 1/x, q = 1/y and solving) - Solving
**Statement Questions**by first forming equations, and then solving
