What is the solution to x - 9 -15?

Answer 1

24

Answer 2

There is not enough information in your question to give an exact value for x, ie x=7 or x=19. This could be because:

(a) The maths question you are trying to answer has more details, but you haven't included them in your question on Answers.com.

or

(b) You are not expecting to discover the exact value of x, but just want to simplify the expression.

Presuming that (b) is true, the only way you can simplify this expression is to combine the two numbers into a single number:

So -9 and -15 add to make -24

Therefore to say x-24 is equivalent to saying x-9-15

You could also correctly say that x - 9 - 15 = x - 24

But as I have mentioned above, this is not "solving" x - 9 - 15, it is just "simplifying" it.
