Question

Which of the following is not a linear equation in one variable? *

a 33z+5
b 33(x+y)
c 33x+5
d 33y+5
​

Answer 1

33( x +y ) is the equation that is not the linear equation in one variable. (Option B)

• The linear equation in one variable can be defined as an equation which can be expressed in the form of ( ax + b = 0), where a and b are two constants also known as integer, and x is a variable that can have only one solution.
• For example, 3x+6 = 30 is a linear equation having variable x in it which can have only one value.
• 33z + 5 has only one variable z. Hence, it is a linear equation in one variable.
• Similarly, 33x + 5 and 33y + 5 both are linear equations in one variable with x and z as a variable respectively.
• 33(x + y) contains two variables x and y and hence it is not a linear equation in one variable. It is a linear equation with two variables.
