X+y=c<br> x−y=a<br><br> solve for x and y
MrRissso [65]

Answer:

x = (c+a)/2

y = (c-a)/2

Step-by-step explanation:

Add the two equations and you get ...

(x +y) +(x -y) = (c) +(a)

2x = c+a

x = (c+a)/2

--

Subtract the second equation from the first and you get ...

(x +y) -(x -y) = (c) -(a)

2y = c-a

y = (c-a)/2

Comment on this problem

This is what I call a "sum and difference" problem. The solution shown here is (obviously) the generic solution to such a problem. Remembering this can get you quickly to the answer any time you're given the sum of two unknowns and their difference.

An important part of any dispensing process is statistical quality control. machines are supposed to dispense on average 600 ml
Ganezh [65]
Given:

Machine dispenser

Average = 600 mL soda to every glass

Volumes recorded in one day (random sampling)

600.15
599.92
599.85
599.92
599.81
600.14
600.04
599.98 

Average = (sum of the volumes)/(number of readings)
               = 4799.81/8
Average = 599.976 mL

Therefore there is sufficient evidence to conclude that the average volume of soda dispenser is different from 600 mL.
