Nina is 10 years younger than deepak. deepak is 3 times as old as nina. which system of equations can be used to find d, deepak's age, and n, nina's age? d = n + 10 d = 3n
d = n − 10 d = 3n
d = n + 10 n = 3d
d = n − 10 n = 3d

Step-by-step explanation:

Let 'd' represents the age of Deepak and 'n' represents the age of Nina.

The given statements : Nina is 10 years younger than Deepak.

Deepak is 3 times as old as Nina.

The equation according to the given statement will be :-

and

Hence, the system of equations can be used to find d, Deepak's age, and n, Nina's age will be :-
