A number x added to 18 would be written x + 18.
The value* of x + 18 would depend on the value x.
For example, if x was 2, x + 18 would equal 20.
if x was 10, x + 18 would equal 28, and so on.
*'Value' means what actual number it comes to.

X/3 + 48 = 3X X + 144 = 9X 8X = 144 X = 18 The number is 18.
6x + 18 = 4 - x 7x + 18 = 4 7x = -14 x = -2
If a number is added to itself, it is twice that number → 18 ÷ 2 = 9 → 9 + 9 = 18
