Answer: x > 10
================================================
Explanation:
We have some unknown number x and we add on 2. The result x+2 is larger than 12, which is written as x+2 > 12
To isolate x, we subtract 2 from both sides. This undoes the operation of "add 2" that happens to x.
x+2 > 12
x+2-2 > 12-2 .... subtracting 2 from both sides
x+0 > 10
x > 10
The unknown number x is larger than 10.
