The sum of a number and 7 is less than 19. What is the number?

Question

This needs to be rewritten then solved step by step please!

Answer 1

Let's write this as an inequality based on the information given, one bit at a time.

"a number" means we should use a variable. Let's call it "x".

"The sum of a number and 7" means we should add 7 to it: "x + 7".

"is less than" means we should use the < comparator, so "x + 7 <".

Lastly, we have 19. So, putting it all together, we have:

x + 7 < 19

There is more than one number for x that makes this inequality true. Can you figure out what they all are?
