1/2x - 7 = 1/3(x - 12)

x = 18

Step-by-step explanation:

Given

x - 7 = (x - 12)

Multiply both sides by 6 ( the LCM of 2 and 3 ) to clear the fractions

3x - 42 = 2(x - 12) ← distribute

3x - 42 = 2x - 24 ( subtract 2x from both sides )

x - 42 = - 24 ( add 42 to both sides )

x = 18

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:
