Carlos is five years older than twice his sister's age. Carlos is 13. Which equation and solution correctly identifies his sister's age?
2x - 5 = 13; x = 9
2x + 5 = 13; x = 4
2x - 5 = 13; x = 4
2x + 5 = 13; x = 9

Answer 1

Answer:

B

Step-by-step explanation:

x=4 so

2x4=8

8+5=13

Carlos's sister is 4 years old, therefore it is B.
