There are thirty-nine 8 text th end text graders in the Kennedy Middle School student council. The number of 8 text th end text graders is twelve fewer than three times the number of 7 text th end text graders in the student council. Which equation can be used to determine n comma the number of 7 text th end text graders in the student council?.

Answer 1

The equation that can be used to determine n is n = 51/3.

What is the equation that can be used to determine the number of 7th graders?

Total number of 8th graders in the council = 3(number of 7th graders) - 12

39 = 3(n) - 12. Where n represents the number of 7th graders

In order to determine the value of n, take the following steps:

Combine similar terms: 39 + 12 = 3n

Divide both sides of the equation by 3 : n = 51/3
