Answer:
x = -6
Step-by-step explanation:
The value of x never changes, no matter what the value of y is, so x = -6 describes every point on the line.
D is correct answer. X stands for adult tickets, y for children
Angle 6&5 are supplementary so they make a line. (Add to 180.)
(3x-34)+124=180 combine like terms
3x + 90=180 subtract 90 from both sides
3x = 90. Divide by 3
X = 30
