1 answer:
First you cross multiply.
2*(b-4)=6b
Then distribute the 2.
2b-8=6b
Minus 2b from each side.
-8=4b
Divide each side by 4.
-2=b
So -2 is your answer.

Solution:
<u>Note that:</u>
- 6x + 26 = 92 (Vertically opposite angle)
- 92 + 92 + z + z = 360
<u>Finding x.</u>
- 6x + 26 = 92
- => 6x = 92 - 26
- => 6x = 66
- => x = 11
<u>Finding z.</u>
- 92 + 92 + z + z = 360
- => 184 + 2z = 360
- => 2z = 360 - 184
- => 2z = 176
- => z = 176/2 = 88
Y=-2/81x^2+50 is the answer
