Craig is x years old. His 15 year old sister, Sue is 6 years younger than Craig. Which equation can be used to determine Craig's age?

What is Craig's age?

x - 6 = 15

Craig is 21 years old

Step-by-step explanation:

x = Craig's age, 15 = Sue's age, and Sue is 6 years younger than Craig, so 15 (Sue's age) is 6 (Years) less than x (Craig's age). The equation is

x - 6 = 15

Using this, x - 6 = 15, we can add 6 to both sides to get x = 21, Craig is 21 years old
