Answer:

x = 3

Step-by-step explanation:

Hi there,

We know that the value of ∠ABD and ∠DBC are the same because BD bisects it. Therefore, we can set both of the angle values equal to each other to find the value of x.

9x = (8x + 3)

x = 3

Hope this answer helps. Feel free to ask questions. Cheers.

5n + 34 = -2 ( 1 - 7n)<br>this is due by midnight.<br><br>NO LINKS PLEASE!
kodGreya [7K]

Answer :

n = 4

Step-by-step explanation:

5n + 34 = -2(1-7n)

first distribute

5n + 34 = -2(1) -2(-7n)

5n + 34 = -2+14n

-5n

+2

then get all of n to the same side

36 = 9n

isolate the variable

36/9 = 9n/9

4 = n
