6(x + y) + (x - y)
<em>use distributive property</em>
= 6x + 6y + x - y
<em>combine like terms</em>
= (6x + x) + (6y - y)
<h3>= 7x + 6y</h3>
Hi there! The answer is B.

Divide both sides of the inequality by -1. Remember that dividing by a negative makes the sign flip.

Therefore, the solution must be bigger than or equal to 8. From the given solution set, the answer is B. {8, 9, 10}

-3(5-6)-4(2-3)
Handling parentheses first:
-3(-1)-4(-1)
Multiplication left to right:
3-4(-1)
3-(-4)
Rewriting the above we have:
3+4=7
