by George I've got it! Thanks

Answer 3

ha no problem

Answer 4

let x = the number. 2 (x +(- 2)) = 16 and x=10

2(4.5+(-2))=5

Have I done something wrong here?

Answer 5

yeah its the sum of the same number times 2 minus 2 equals 16
2(x+x)-2=16
to find it one does the opposite add 2 divde by 2 and divide again by 2 hence 4.5

Answer 6

I think I will just let it go at that.

Have a good day.
