Can some pleaseeee help me answer this

7

Step-by-step explanation:

Given : Total number of models Curt has = 12

Curt has 5 more model cars than boats .

Number of models of car =3

Let x be the number of boats he has , then the number of models of cars he has will be x+5 .  (1 )

According to the question , we have

Subtract 8 from both sides, we get

Divide both sides by 2, we get

Now, the number of models of cars = 2+5=7      [From (1)]

Hence, Curt has 7 models of cars.
