Answer:
Division
Step-by-step explanation:
Since d is multiplied by 5, we have to divide it by 5 to get the answer.
And you have to do it on both sides.
5d÷5=d
75÷5=15
So,
d=15
I call the apple pies is a and hamburger is b so:
4a + 3b = 47
6a + 5b = 75
a = (47 - 3b)/4
6 ((47- 3b) /4) + 5b = 75
6(47- 3b) +20b = 300
282 - 18b + 20b = 300
2b = 18
b = 9
We have 4a + 3b = 47 and we have the value of b so:
4a + 3.9 = 47
4a = 20
a = 5
The apple pie is 5$ and the hamburger is 9$
