Step-by-step explanation:

given ,x+y=12

x^2+y^2=74

x=12-y

(12-y)^2+y^2=74

144+y^2-24y+y^2=74

2y^2-24y+70=0

y^2-12y+35=0

y^2-7y-5y+35=0

y(y-7)-5(y-7)=0

y=5 and y= 7

their ages are 5 and 7 . if you take 5 you will get 7. if you take 7 you will get 5 . both are correct.

5+7=12

5^2+7^2=25+49=74
