Three small shipping boxes and one large shipping box hold 64 pounds. A large shipping box minus a small shipping box holds 32 pounds. When writing a system of equations to determine how many pounds each small box (x) and each large box (y) holds,
which statements are true?

the answer is a.

135 and 80

step-by-step explanation:

a

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a

in order to do a equation you have to get what has has a letter to one side and for a traversal you have to know that each line is the same as each opposing side
