The given equation is expressed as

x + 3 = 2x - 18

Subtracting x from both sides of the equation, it becomes

x - x + 3 = 2x - x - 18

3 = x - 18

Adding 18 to both sides of the equation, it becomes

3 + 18 = x - 18 + 18

21 = x

x = 21

Since there is only one value for x, the correct option is

a. A single solution
