Aseem and Stana are building model cars. Stana's car is 5 less than 2 times the length of Aseem's car. The sum of the lengths of both cars is 20 inches. Write an equation to determine the lengths of Aseem's and Stana's cars.

Respuesta :

Answer:

3x - 5 = 20

Step-by-step explanation:

Let x be the length ( in inches ) of  Aseem's car,

Since, Stana's car is 5 inch less than 2 times the length of Aseem's car.,

So, the length of  Stana's car = 2x - 5

Total length of both car = x + 2x - 5 = 3x - 5

According to the question,

Total length of the both car = 20 inches,

3x - 5 = 20

Which is the required equation.
