Question 526415
Maya was brother was 12 when she was born. The sum of their ages is 22. Find their ages.

Let
Present age of Maya = m
Present age of Brother = b

Maya is 12 years older than her brother

m=b+12.....(1)


Sum of their ages is 22
m+b=22.....(2)

Put the value of m from (1) to (2)
b+12+b=22
2b=22-12
2b=10
b=10/2
b=5

Plug in the value of b in (1)
m=5+12
m=17


Present age of Maya = m = 17 years old
Present age of Brother = b = 5  years old
