Step 1: Simplify the equation
2x+1=x+3
Step 2: Subtract x from both sides to get all x-terms on one side.
2x−x+1=3
x+1=3
Step 3: Subtract 1 from both sides to isolate x.
x=3−1
x=2
Conclusion:
The solution to the equation is x=2x = 2x=2, so the correct answer is (c) 2. This question related to Chapter 4 Mathematics Class 9th NCERT. From the Chapter 4 Linear Equation in Two Variables. Give answer according to your understanding.
