Hi there! The answer is B.
![5r \leqslant 6r - 8](https://tex.z-dn.net/?f=5r%20%5Cleqslant%206r%20-%208)
Subtract 6r from both sides.
![- r \leqslant - 8](https://tex.z-dn.net/?f=%20-%20r%20%5Cleqslant%20%20-%208)
Divide both sides of the inequality by -1. Remember that dividing by a negative makes the sign flip.
![r \geqslant 8](https://tex.z-dn.net/?f=r%20%5Cgeqslant%208)
Therefore, the solution must be bigger than or equal to 8. From the given solution set, the answer is B. {8, 9, 10}
~ Hope this helps you!
First, we write the first equation where the left side contains x and y in the right side. We do as follows:
x = 2y + 6
You, then substitute the equation to the second one.
3(2y + 6) + y = 8
6y + 18 + y = 8
7y = -10
y = -10/7
x = 22/7
