Answer:

The integers are -5 , -6 ⇒ answer C

Explanation:

* Lets explain the meaning of consecutive numbers

- Consecutive numbers are numbers that follow each other in order.

- They have a difference of 1 between every two numbers

- Consider that the smaller of two consecutive integer is n, then the

larger one will be n + 1

* In the problem

∵ The larger of the two consecutive integers is 7 greater than twice

the smaller

- That means the larger one is 7 plus twice the smaller

∵ The smaller one is n

∵ The larger one is n + 1

∴ n + 1 = 2(n) + 7

∴ n + 1 = 2n + 7

- Subtract n from both sides

∴ 1 = n + 7

- Subtract 7 from both sides

∴ -6 = n

∴ The smaller number is -6

∵ The greater number is n + 1

∴ The greater number = -6 + 1 = -5

* The integers are -6 , -5
