The number 6 is halfway between-12 and what?

Set up an equation:

(-12 + x) / 2 = 6

Multiply 2 to both sides:

-12 + x = 12

Add 12 to both sides:

x = 24

So the number between - 12 and x is 6, that means that if you add the 2 numbers together, then divide by 2, then you will get 6 so

(-12+x) / 2=6

multiply both sdies yb 2

-12+x=12

add 12 to both sdies

x=24

so 6 is halfway between - 12 and 24
