Let the price of 1 liter of milk be m, and let the price of 1 loaf of bread be b.
3 liters of milk cost 3m.
5 loaves of bread cost 5b.
The total is $11.
That gives us the first equation:
3m + 5b = 11
4 liters of milk cost 4m.
4 loaves of bread cost 4b.
The total is $10.
That gives us the second equation:
4m + 4b = 10
We have a system of two equations.
3m + 5b = 11
4m + 4b = 10
Multiply the first equation by -4.
Multiply the second equation by 3.
Then, add the equations.
-12m - 20b = -44
+ 12m + 12b = 30
---------------------------
-8b = -14
b = 14/8 = 7/4 = 1.75
Now substitute b with 1.75 in the first original equation.
3m + 5b = 11
3m + 5(1.75) = 11
3m + 8.75 = 11
3m = 2.25
m = 0.75
Answer: A liter of milk costs $0.75, and a loaf of brad costs $1.75.
Answer:
x(aka the number) = -16
This is because 4 times -16 = -64, and -64 plus 57 = -7.
