Question

Which of the following is a linear equation in one variable?
1. 2x + 1 = y – 3
2. 2x – 1 = x2
3. X2 – x + 1 = 0
4. 2t – 1 = 2t + 5

Answer 1

Answer:

ans is 2 how to ans give 2 tell me

Answer 2

Step-by-step explanation:

Correct option is

B

2t−1=3t+5

A linear equation in one variable is an equation that can be written in the form ax+b=c, where a,b are real numbers.

option (a) has two variables x and y.Hence it is a linear equation with two variables.

Option (b) has one variable t. Hence it is a linear equation with one variable

Option (c) and (d) is not a linear equation ∵ the highest power of x is 2.

Hence, option B is correct.
