hello :
2x+7y=1 ...(*)
y=4x−8...(**)
(4;8) means x= 4 and y= 8
put this values in (*) and(**) :
2(4)+7(8) =1 62=1 false
8=4(4)-8 8=8 true
so :(4;8) is not solution for this system.

Answer:
Step-by-step explanation:
It appears that the number of bulbs produced on the first shift is quite a bit more than the second shift. 5.5 times more, actually. That means that the first shift's output is based on the second shift's output. Second shift produced an unknown number of bulbs, so we will call that number x. First shift produced 5.5 times more, so first shift produced 5.5x. The total number of bulbs produced between the 2 shifts is given as 16,250, so
x + 5.5x = 16,250 so
6.5x = 16,250 and
x = 2500
The second shift produced 2500 bulbs, and the first shift produced 5.5(2500) = 13,750 bulbs.
