Answer:
x = 7
Step-by-step explanation:
5x + 9 = 6x + 2
5x - 6x = 2 - 9
-x = -7
probe:
5*7 + 9 = 6*7 + 2
35 + 9 = 42 + 2 = 44
x = 11
The angles shown are alternate exterior angles. If they are equal, then the lines are parallel
5x+9 = 6x-2
Subtract 5x from each side
5x-5x+9 = 6x-5x-2
9 = x-2
Add 2 to each side
9+2 = x
11 =x
