If x is the number of years, then the equation is ______
The answer is _____

Respuesta :

Sara = 8 years old
Mom = 34 years old

Let the number of years be x when Sara will be twice as young as her mom will be.
2(8 + x) = 34 + x
16 + 2x = 34 + x
2x - x = 34 - 16
x = 18

Answer:
If x is the number of years, then the equation is 2(8 + x) = 34 + x
The answer is 18
