Quizplus · Accepted Answer

Let the second number be x. Then the first number is 3x - 8. The equation for their sum is x + (3x - 8) = 16, which simplifies to 4x - 8 = 16. Solving for x gives x = 6. Substituting x = 6 into the expressions for the two numbers gives the first number as 3(6) - 8 = 10 and the second number as 6. Therefore, the numbers are 6 and 10.
