Answer 1

Given:

Yamir is twice as old as Pato.

In three years, the sum of their ages will be 30.

Pato's current age is represented by $a$.

To find:

The equation that could be used to correctly solve for $a$.

Solution:

We know that, Pato's current age is represented by a, then

Yamir's age = $2a$

After three years,

Pato's age = $a+3$

Yamir's age = $2a+3$

In three years, the sum of their ages will be 30.

$(a+3)+(2a+3)=30$

$(a+2a)+(3+3)=30$

$a+2a+6=30$

Therefore, the correct option is 2.
