The sum of two numbers is 39. the second number is 3 more than three times the first number. let x represent the first number and let y represent the second number. what is the value of the first number? 4 5 6 9

Answer with Step-by-step explanation:

The sum of two numbers is 39.

Let x represent the first number and let y represent the second number.

⇒ x+y=39

The second number is 3 more than three times the first number.

⇒ y=3x+3

Putting y=3x+3 in x+y=39

⇒ x+3x+3=39

⇒ 4x=39-3

⇒ 4x=36

Dividing both sides by 4, we get

x=9

Hence, Value of first number is:

9
