The sum of Cameron’s and Celestria’s age is 42. Celestria is twelve less than twice as old as Cameron. What are their ages?
1 answer:
Answer:
Cameron is 18. Celestria is 24.
Step-by-step explanation:
Ca + Ce = 42
Ce = 2(Ca) - 12
Plug in Ce to first equation.
Ca + (2(Ca) - 12) = 42
Ca + 2Ca - 12 = 42
3Ca - 12 = 42
3Ca = 54
Ca = 18
Cameron is 18.
Plug in Cameron's age into either equation.
18 + Ce = 42
Ce = 24
Celestria's age is 24.
