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.
