A. 33
B. 33(x+y)
C. 33x
D. 33y
Answers
B.33(x+y) is not a linear equation
What is a linear equation?
Linear equation is an equation that has the maximum power of variable as 1. It is also known as a one-degree equation.
Linear equation in one variable
An equation that has only one variable involved is known as a linear equation in one variable. Such as X+2=5
Explanation for correct option
B.33(x+y) is the correct option because it has two variables e.g. x and y.
Explanation for incorrect option
A.33 is incorrect because it does not have any variable.
Explanation for incorrect option
C.33x is incorrect because it has one variable involved e.g. x
Explanation for incorrect option
D.33y is incorrect because it has only one variable involved e.g. y
