Question

2 more than a number equal to 30

Answer 1

You are looking for an number. Let's call the unknown number x.

2 more than a number means 2 more than x. That means 2 added to x, or x + 2.

We are told that that sum is equal to 30. The equation then is:

x + 2 = 30

Now solve for x. You want x alone, so subtract 2 from both sides to get:

x + 2 - 2 = 30 - 2

x = 28

The number is 28.
