1.
3n + 5 = 6
3n = 6 - 5
3n = 1
n = 1/3
2.
4 + 5x = 1
5x = 1 - 4
5x = -3
x = -3/5
3.
4y - 15 = -10
4y = -10 + 15
4y = 5
y = 5/4
4.
3 - 4d = 13
-4d = 13 - 3
-4d = 10
d = -10/4
d = -5/2
5.
8 = 9x - 7
8 + 7 = 9x
15 = 9x
15/9 = x
5/3 = x
hope this helped, God bless!

Answer:
y = 100°
Step-by-step explanation:
I can't see the full question, but I'm guessing you need to find the measure of angle y.
The total angle sum of a polygon can be calculated with the formula
T = 180°(n - 2) where T is the total angle measure, and n i the number of sides.
For our shape, there are 4 sides, so n = 4. Plug that in and simplify...
T = 180°(4 - 2)
T = 180°(2)
T = 360°
We are given 3 of the angles, so angle y is
y = 360 - 107 - 104 - 49
y = 100°
Answer:
87
Step-by-step explanation:
Do what's inside the paranethesis first
2+(9*3)=2+27=29
29*3=87
