Answer:

A number: since we don't know what the exact number is we can represent that number with a variable. Let's use x...

x + (-3) = 8

You can also write this as...

x - 3 = 8

They both mean the same thing :)

When you solve...

x - 3 = 8

add 3 on both sides...

x = 11

Your answers are...

x + (-3) = 8

x = 11

Hope this helps :)
