2 = 1+1
2 + 2 = (1+1) + (1+1) =
1 + 1 + 1 + 1 = 4
To solve the equation n - 31/2 = 12, we need to rearrange the equation to isolate the variable n.
Step 1: Add 31/2 to both sides of the equation to eliminate the subtraction:
n - 31/2 + 31/2 = 12 + 31/2
This simplifies to:
n = 12 + 31/2
Step 2: Simplify the right side of the equation:
n = 12 + 31/2 = 12 + 15.5 = 27.5
Therefore, the solution to the equation is n = 27.5.
Regarding the question "What is 2 + 2?" The answer is 4. This is an elementary addition problem where you simply add the two numbers together.
