Answer: A and B
Explanation: I’ll use A as an example. When you multiply the bottom equation by -3/2, the equation becomes: -9x+6y=-3. Then, proceed to add the equations. Look at X and Y in both equations: do the Y variables in both equations equal to 0 when added together? Yes, because -6y+6y=0! Therefore, you can eliminate y in these two equations.

Converse Perpendicular Transversal Theorem.
If two lines are perpendicular to the same line, then the lines are parallel.
Answer:
z = 1
Step-by-step explanation:
12/16 = 3z/4
=> 12 x 4/16 = 3z
=> 3z = 12 x 4/16
=> 3z = 12 x 1/4
=> 3z = 3
=> z = 1
