eggs have 6+grams of protein and 77 calories:
milk has 8 grams of protein and 168 calories

if the number of eggs is x and the number of glasses of milk y
eggs have 6+grams=>6x grams of protein and 77x calories
milk have 8+grams=>8y grams of protein and 168y calories
to keep alive you must consume 36 grams of protein and+658 calories per day
36 grams of protein :
6x%2B8y=36.............eq.1
+658 calories :
77x%2B168y=658............eq.2
solve the system:
6x%2B8y=36.............eq.1
77x%2B168y=658............eq.2
----------------------------------------------------------
start with
6x%2B8y=36.............eq.1.....solve for y
8y=36-6x
y=36%2F8-6x%2F8
y=4.5-0.75x......eq.1a
substitute in eq.2
77x%2B168%284.5-0.75x%29=658............eq.2....solve for x
756-49x=658
756-658=49x
98=49x
x+=+2
go to eq.1a
y=4.5-0.75x......eq.1a, substitute 2 for x and solve for y
y=4.5-0.75%2A2
y=4.5-1.5
y+=+3

you must consume 2 eggs and 3 glasses of milk each day to stay alive
check:calories
2%2A77%2B3%2A168=658
154%2B504=658
658=658
check: proteins
6%2A2%2B8%2A3=36
12%2B24=36
36=36

Using Simultaneous equations how many eggs and glasses of milk must you consume each day to stay alive.
=================
9 or more eggs would be sufficient.
Or 4.5 or more glasses of milk.
Other combinations are possible.

Now that the other person has written an EXTREMELY CONFUSING and TIME-CONSUMING NOVEL, let me show you the EASY way.



Let number of eggs and glasses of milk be E and M, respectively

Then we get: 6E + 8M = 36 ---- eq (i)

Also, 77E + 168M = 658_____7(11E + 24M) = 7(94)_____11E + 24M = 94 ---- eq (ii)

18E + 24M = 108 ----- Multiplying eq (i) by 3 ------ eq (iii)

7E = 14 ----- Subtracting eq (ii) from eq (iii)

E, or 



3(2) + 4M = 18 ----- Substituting 2 for E in eq (i)

6 + 4M = 18

4M = 12

M, or 

That's IT!! Nothing CONFUSING or COMPLEX!
