Answer:
the cost of a liter of milk is $0.75
the cost of a loaf of bread is $1.75
Step-by-step explanation:
Let
x------> the cost of a liter of milk
y------> the cost of a loaf of bread
we know that
------> equation A
------> equation B
Multiply equation A by
-------> equation C
Multiply equation B by
------> equation D
Adds equation C and equation D
Find the value of x
substitute the value of y in the equation A
27 and 36
12 is too short to be multiplied by 9, 21 can be multiplied by 3 but not 9 again, 3 can’t go into 45. Which leaves 27 and 36. 3 times 9 equals 27. 3 times 12 equals 36, 9 times 4 equals 36.
