Answer:
Final answer is x=90, 
Step-by-step explanation:
Given equations are:
-x-4y=37 ...(i)
-2x-4y=-53 ...(ii)
multiply (ii) by -1
2x+4y=53 ...(iii)
Add (i) and (iii)
x=90
plug value of x=90 into (i)
-x-4y=37
-90-4y=37
-4y=37+90
-4y=127

Hence final answer is x=90,

Answer:
c/a
Step-by-step explanation:
The product of two solutions from the quadratic formula is c/a.
20,000 x 25 = 500,000
500,000 divided by 100 = 5,000 members are lost.
Members left = 15,000
Members added = 10,000
Members every year = Members left + Members added
= 15,000 + 10,000
= 25,000
