Answer 6

What does it mean when it says find the value of x - 8?

Answer 7

well you know that x = -2, so replace x with -2 to get

Answer 8

the value of x-8 is -10 (since x = -2)

Answer 9

x is just a number (a place holder for a number)

so is x-8 because subtracting 2 numbers results in another number

Answer 10

@gold_grace123 so if your answer is x=-2, then you'll have (-2)-8=-10 :)
