Solution

The correct option is A 1
The unknown is x
We need to solve x by isolating it to one side of the equation

2x+1=3
Step 1: Subtract 1 from both sides of the equation to eliminate the constant on the left side of the equation.
2x+11=31 2x=2

Step 2: Now, divide both sides by 2 to eliminate 2 on the left side of the equation.
2x2=22 x=1

Hence, x=1
