Answer 1

This is the answer of your second question.

Step-by-step explanation:

Solution :-

Let the present ages of Tany and Dazzy be 5x years and 9x years.

8 years later ,

The age of Tany = (5x+8) years

The age of Dazzy = (9x+8) years

According to question,

:⟹(5x+8)+(9x+8)=86

:⟹5x+8+9x+8=86

:⟹14x+16=86

:⟹14x=86−16

:⟹14x=70

:⟹x= 14/70

:⟹ x=5
