Question

7 more than twice a number is greater than negative 13

Answer 1

2x+7>-13

Explanation:

Let the unknown number be x.

Since the problem starts off with "7 more than twice a number," we need to find twice the number first. Let's multiply x by 2:

we end up with 2x.

Let's return to "7 more than twice a number..."

This means that the value is 7 more than 2x, so let's add 7 to 2x:

we end up with 2x+7.

Now, let's take a look at "...is greater than negative 13."

Our new value, 2x+7, is greater than -13.

So, we can write:

2x+7>-13
