If you use the first answer, the equation becomes 2x + 2y = 16. You could subtract this from equation Q to eliminate x.
The second answer makes equation P -2x - 2y = -16. You could add this to equation Q to eliminate x. You can use both of these methods to eliminate the x term, but if you can only choose one, you should choose the second option.

Answer:
w = 
Step-by-step explanation:
Reverse the equation placing w on the left side
8w - 3 = - 12u + 13 ( add 3 to both sides )
8w = - 12u + 16 ( divide both sides by 8 )
w =
x/2 = -0.73
To solve for x multiply both sides by 2:
x = -1.46
