26 - x = 17
What does x equal?

x = 9

We know that 26 and 17 are in a fact family.

Let's see the fact family.

26 - 17 = 9.

So, the answer is 9.

Hope this helps you!

x = 9

Step-by-step explanation:

-x = 17 - 26                       Take the numbers to one side and leave the letters                                                       on the other side

-x = -9                                    Subtract the numbers

x = 9                       since the x and the 9 are negative they become positive

                              (two negatives equals a positive only when multiplying or

                               dividing and in this case you are dividing the -1x to both

                               sides)

its c or d   take a lucky guess my dude

-2 is the right
