Answer:
17b - 2
Step-by-step explanation:
5b - 5 - 12b - 7
Say bye to the 12b, and add 12 to it and the 5.
5b + 12 = 17b
17b - 5 - 7
Add 5 to the 5 and the -7.
-7 + 5 = -2.
Now you have 17b - 2. You can’t go farther, so there’s your answer.
I'm pretty sure all of that sounds s 9
Answer-44
You can turn both of the denominators ( bottom numbers on the fractions ) into 120 ( the whole number ) and the top numbers can be multiplied by how many times the denominators went into 120. Then add the top numbers which equals 76 and then 120-76=44. Hope that kinda helps !!

Answer:
The answer to your question is:
x = 21
y = 4
∡ = 75° and 105°
Step-by-step explanation:
Process
3(x + y)° + 5x = 180 supplementary angles
3(x + y) = 4x - 9 corresponding angles
Expanding
3x + 3y + 5x = 180 (1) Like terms
3x + 3y = 4x - 9 (2)
8x + 3 y = 180 (1)
8 ( -x + 3 y = -9) (2) Multiply by 8
8x + 3y = 180 (1)
-8x +24y = -72 (2) Elimitation method
27 y = 108
y = 108 / 27
y = 4
8x + 3 (4) = 180
8x +12 = 180
8x = 168
x = 21
3(21 + 4) = 3(25) = 75°
5(21) = 105°
