Respuesta :

Billy age is 10 years less than 2 times Charlie's age. If Billy is 36 years old, how old is Charlie?

Billy's age = B = 36

Charlie's age= C

10 years less means minus 10, and two times means multiplied by 2.

B = 2C-10

Since B = 36

36= 2C-10

Solving for C:

36+10 = 2C

46=2C

46/2 =C

C= 23

Charlie is 23 years old.
