The real numbers x and y satisfy the equations: xy - x = 180 and y + xy = 208.
Let the two solutions be (x1, y1 and (x2, y2).
What is the value of x1 + 10y1 + x2 + 10y2

The value of is 317.

Step-by-step explanation:

Let the system of nonlinear equations be:

(1)

(2)

From (1), we clear :

Let apply this resulting expression in (2):

By the Quadratic Formula we obtain the solution of the second order polynomial:

and

And the respective values of are, respectively:

If we know that , , and , then the value of is:

The value of is 317.

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:
