Question

Write true or false.
An equation may or may not contain variables.
An equation in which the highest power of the variable(s)
is 2 is called a linear equation.
A linear equation that has only one variable is called a linear
equation in one variable.
4x > 16 is a linear equation.
7a + 7b = 56 is a linear equation with one variable.​

Answer 1

Answer:

Correct option is

B

2t−1=2t+5

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