Question

The sum of 3 numbers is 62. The first number can be represented by the variable x. The second number is 7 more than the first number, and the third number is 3 times the first number. What is the third number?

Answer 1

Answer:

The third number = 33

Step-by-step explanation:

First number = x

Second number = x + 7

Third number = 3x

x + x + 7 + 3x = 62              Combine like terms

5x + 7 = 62                          Subtract 7 from both sides

5x = 62 - 7

5x = 55                                Divide by 5

5x/5 =  55/5

x = 11
