The sum of three numbers is 45. the second of the three numbers is three more than twice the first number, x. the third number is two more than the first number, x. which equation can be used to solve for the first number, x?

x + (2x + 3) + (x + 2) = 45

Step-by-step explanation:

Here, x represents the first number,

Since, second number is three more than twice the first number,

⇒ Second number = 2x + 3,

The third number is two more than the first number,

⇒ Third number = x + 2

Thus, the sum of these numbers = x + (2x + 3) + (x + 2)

According to the question,

Total sum = 45

⇒ x + (2x + 3) + (x + 2) = 45

Which is the required equation.
