2/3p-7=1/4p+12 help me please

p=228/5

Step-by-step explanation:

2/3p-7=1/4p+12

12(2/3p-7)=12(1/4p+12)

8p-84=3p+144

5p-84=144

5p=228

p=228/5

Check:

2/3(228/5)-7=1/4(228/5)+12

30.4-7=11.4+12

23.4=23.4

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
