Step-by-step explanation:
5 is not function because an x cannot map on 2 different y's
Answer:
![2(y+2)](https://tex.z-dn.net/?f=2%28y%2B2%29)
Step-by-step explanation:
Let
y --->Mala's age
x---> sister's age
we know that
---> equation A
so
The sum of ages of the sisters is
![x+y](https://tex.z-dn.net/?f=x%2By)
substitute equation A in the expression of the sum of ages
![(y+4)+y=2y+4](https://tex.z-dn.net/?f=%28y%2B4%29%2By%3D2y%2B4)
simplify
![2(y+2)](https://tex.z-dn.net/?f=2%28y%2B2%29)
361 + 173 =361+173
(a+b)+(a-b)=361+173
a+b=a-b=534
2a=534
a=267
267+b=361
b=94
the two numbers are 267 and 94
