Answer 1

Step-by-step explanation:

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.
