Answer:
(C) (2, -2)
Step-by-step explanation:
Given the linear equation: 
A second linear equation is given by the table:

Clearly, this is a graph of y=-x as each y-value is a negative of its x-value.
Therefore if:

Recall: y=-x
Therefore: y= -2
Therefore, a solution to the system of equations is (2, -2)

Answer: 3/4w
Explanation:
1/2(w-6)+1/4(w+12)
= 1/2w-6/3 + 1/4w+12/4
= 1/2w-3 + 1/4w+12/4
= 1/2w +1/4w
= 2/2(1/2)w + 1/4w
= 2/4w+1/4w
=3/4w
