Twice the difference of a number and 9 is equal to 2

Question

i really need help im getting this wrong.

Answer 1

2(x-9) = 2

2x-18 = 2

2x = 20

x = 10

or

2(9-x) = 2

18-2x = 2

2x = 16

x = 8

x = 8 or 10

the "difference" usually means the absolute value of the difference between the two numbers

2|x-9| = 2

then x= 8 or 10
