Explanation:
(a)
3x + 5y = 8 → (1)
4x - 3y = 1 → (2)
multiplying (1) by 3 and (2) by 5 and adding the result will eliminate y
9x + 15y = 24 → (3)
20x - 15y = 5 → (4)
add (3) and (4) term by term to eliminate y
29x + 0 = 29
29x = 29 ( divide both sides by 29 )
x = 1
substitute x = 1 into either of the 2 equations and solve for y
substituting into (1)
9(1) + 15y = 24
9 + 15y = 24 ( subtract 9 from both sides )
15y = 15 ( divide both sides by 15 )
y = 1
solution is x = 1 , y = 1
-----------------------------------------
(b)
6p + 4q = 20 → (1)
5p - 2q = 6 → (2)
multiplying (2) by 2 and adding to (1) will eliminate q
10p - 4q = 12 → (3)
add (1) and (3) term by term to eliminate q
16p + 0 = 32
16p = 32 ( divide both sides by 16 )
p = 2
substitute p = 2 into either of the 2 equations and solve for q
substituting into (1)
6(2) + 4q = 20
12 + 4q = 20 ( subtract 12 from both sides )
4q = 8 ( divide both sides by 4 )
q = 2
solution is p = 2 , q = 2

I guess "disgusting" should work here. :)
Answer:
My colleagues A, B, and I DESIGNED an experiment to test the impact on worker perceptions of well being when domesticated cats ARE ALLOWED to freely roam various work environments in which the subjects were normally employed. Their test environments WHICH WERE SELECTEE for our experiments: a law office, a laboratory in which experiments ARE PERFORMED using laboratory rats, and an automobile assembly line. One-way mirrored glass pannels WERE INSTALLED to allow video cameras to record the activity and researchers to observe the same and take notes. We secretly inserted observers directly into the work environment. These observers posed as outside contractors and WORE UNIFORM as a maintenance and cleaning staff, coffee and water service vendors, and similar suporting personnel. The observers DREW from the students who MATRICULATED into the experimental psychology courses from which this STUDY WAS DEVELOPED as an example of such studies generally.
