This document defines and provides examples of first degree equations, which are equations where the highest exponent of any variable is 1. All linear equations are first degree. An example first degree equation is 3x + 5 = 6. To identify a first degree equation, one checks which options have the highest exponent being 1. The option 8x - y = 3 is a first degree equation, while the others are not.

1. FIRSTDEGREEEQUATIONIN ONEVARIABLE
DEFINITION:
 The Equations in which the highest exponent is 1 are called the First Degree Equations.
 All linear equations are first degree equations.
 Equation of a straight line is a first degree equation.
EXAMPLES OF FIRST DEGREE EQUATIONS
Considerthe equation3x + 5 = 6.
The highestexponentof the variablesinthisequationis1.
So,3x + 5 = 6 is a firstdegree equation.
SOLVED EXAMPLE ON FIRST DEGREE EQUATIONS
Ques: Identify the first degree equation from the following.
Choices:
A. 8x � y = 3
B. 5x + 4x2 = 7x
C. 7x3 � 8x2 + 9x + 3 = 0
D. x2 + 2x + 1 = 0
Correct Answer: A
SOLUTION:
Step 1: The equations in which the highest exponent is 1 are called the first degree
equations.
Step 2: Here, only 8x � y = 3 has 1 as its highest exponent.
Step 3: So, 8x � y = 3 represent a first degree equation.
