Question

2

The sum of the ages of Cesar and Rosa is 72 years. 6 years ago, Cesar's age was 2 times Rosa's age. How old
is Cesar now?
ears old

Answer 1

I think his age is 39.

Explanation:

If Cesar's age was 2 times Rosa's 6 years ago, that means their combined ages 6 years ago was 66. 66 dived by 2 is 33 and 33 plus the 6 years is 39.

Answer 2

Cesar is now 46

Explanation:

c=Cesar

r=Rosa

c+r=72, r=72-c

six year ago,

c-6=2(r-6)

c-6=2(72-c-6)

c-6=2(66-c)

c-6=132-2c

c+2c=132+6

3c=138

c=46

to check

r=72-46=26

26+46=72
