The pattern seems to be add 2, then divide by 2.
7+2=9
It's probably 9
-7y > 161......here, u would divide both sides by -7...keep in mind, when dividing/multiplying by a negative number, the inequality sign changes.
y < 161/-7
y < -23
7y > -161...here u divide by 7
y > -161/7
y > -23
Answer:

Step-by-step explanation:
(2x + 3) (-x - 2)
distribute first term, to the second term:
2x(-x) + 2x(-2) + 3(-x) + 3(-2)
multiply:
+ (-4x) + (-3x) + (-6)

combine the like terms:
- 4x - 3x - 6
-7x
- 7x - 6
final answer :
- 7x - 6
hope this helped !!
mark me brainliest :D
well if that's in a math problem then its division. Because you are sharing equally.
2x + 3 + x = 39
3x + 3 = 39
3x = 36
x = 12
