Answer and Step-by-step explanation:
To solve, we would set the first number to x, and make an equation.
<u>Solve for x.</u>
x + (x - 6) + 3x = 69.
<u>Add and combine like terms.</u>
2x + 3x - 6 = 69
5x - 6 = 69
<u>Add 6 to each side of the equation.</u>
5x = 75
Divide by 5 to both sides.
x = 15
<u>The first number is 15.</u>
<u>The second number is (x - 6) = (15 - 6) = 9.</u>
<u>The third number is 3x = 3(15) = 45.</u>
