Joseph and Ashley went to a store. Joseph bought 3 boxes of cupcakes and 2 boxes of brownies for $19. Ashley bought 2 boxes of cupcakes and 4 boxes of brownies for $24. Let x represent the price of a box of

cupcakes and y represent the price of a box of brownies.

Write a system of linear equations that describes the situation.

On the set of axes below, graph the system of equations.

Determine the exact cost of one box of cupcakes and the exact cost of one box of brownies in dollars and

cents. Explain how you got your answer. (Hint: You can use the graph to help you, a table in calculator, or

elimination method if you like)

step-by-step explanation:

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
