Question

Question 4. Find out which of the following are examples of linear equation in one variable.
2x + 4, 2xy - 3, x?, (x + 1)(x - 1), (2x + 1), (yzx - 9)​

Answer 1

x - 2 = 7

Solution:

Given, x – 2 = 7

By adding 2 to both sides, we get

x – 2 + 2 = 7 + 2

⇒ x = 7 + 2

⇒ x = 9

Answer 2

Answer:

2xy-3 is a linear equation
