For which equations is 8 a solution? Check all that apply.
x+6=2
X+ 2 = 10
X-4=4
X-2 = 10
2x=4
3x = 24

1

see explanation

Step-by-step explanation:

Solving each equation

x + 6 = 2 ( subtract 6 from both sides )

x = - 4 ≠ 8

x + 2 = 10 ( subtract 2 from each side )

x = 8 ← True

x - 4 = 4 ( add 4 to both sides )

x = 8 ← True

x - 2 = 10 ( add 2 to both sides )

x = 12 ≠ 8

2x = 4 ( divide both sides by 2 )

x = 2 ≠ 8

3x = 24 ( divide both sides by 3 )

x = 8 ← True

The equations where x is a solution are

x + 2 = 10 , x - 4 = 4 and 3x = 24

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:
