Solve the system.
x=5y
y=22-2x

What is the solution?

{x,y} = {10,2}

Step-by-step explanation:

Solve equation [2] for the variable  y

[2]    y = -2x + 22

Plug this in for variable  y  in equation [1]

[1]    x - 5•(-2x+22) = 0

  [1]    11x = 110

Solve equation [1] for the variable  x

  [1]    11x = 110

  [1]    x = 10

By now we know this much :

   x = 10

   y = -2x+22

Use the  x  value to solve for  y

   y = -2(10)+22 = 2

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:
