NCERT Solutions for Class 8 Maths Chapter 2 Linear Equations in One Variable Exercise 2.1

Examples From Chapter 2 Linear Equations in One Variable

Ex. 1 Solve the equation: 5t – 3 = 3t – 5

Soln: 5t – 3

= 3t – 5
Therefore,

5t – 3t = (-5 )+ 3 . . . . [Transposing 3t to L.H.S. and –3 to R.H.S.]
2t = (–2)

t= (-1)

Ex. 2 Fill in the blanks:

1. A polynomial of degree 1 is called a _______.
2. Another name for an equation’s solution is ____________.
3. A combination of constants and variables, connected by basic operations is called ________.

Soln: 

1. Linear polynomial
2. Root
3. Algebraic Expression
