Step 1: Understanding the Equation
To solve the equation 2x + 1 = 3, we need to isolate the variable x. This means we will manipulate the equation until x is alone on one side.
Step 2: Subtracting 1 from Both Sides
- First, we subtract 1 from both sides of the equation to eliminate the constant on the left side.
- The equation now looks like this:
2x + 1 - 1 = 3 - 1
- Simplifying this gives:
2x = 2
Step 3: Dividing by 2
- Next, we need to isolate x by dividing both sides of the equation by 2.
- This gives us:
2x/2 = 2/2
- Simplifying this results in:
x = 1
Step 4: Conclusion
- We have found that the value of x is 1.
- To verify our solution, we can substitute x back into the original equation:
2(1) + 1 = 3
- Simplifying the left side:
2 + 1 = 3, which is true.
- Therefore, the solution is confirmed.
Final Answer
- The value of x is 1.
- This process shows how to solve linear equations step by step, ensuring a clear understanding of the operations involved.

We are using transposition method for this ques so
2x+1=3
2x =3-1
2x =2
x. =2/2. (we will cancel out 2 with out)
x. =1
therefore, x is equal to 1
