Answer 3

To solve the equation X-12=21 in 2nd grade, we can follow these steps:

Step 1: Isolate the variable X on one side of the equation. Step 2: Simplify to find the value of X.

Let's solve the equation:

Step 1: Isolate the variable X

To get X alone on one side of the equation, we need to move the constant term (-12) to the other side. To do this, we can perform the inverse operation, which is adding 12 to both sides of the equation:

X - 12 + 12 = 21 + 12

Step 2: Simplify to find the value of X

Now, we simplify both sides of the equation:

X = 33

So, the solution to the equation is X = 33.
