PLS HELP
I WILL MARK BRAINLIEST!!
A fruit company delivers its fruit in two types of boxes: large and small. This morning, the company made two deliveries. The table below shows the number of boxes in each delivery and the total weight (in kilograms).
Let x be the weight (in kilograms) of each large box.
Let y be the weight (in kilograms) of each small box.

(a). Write a system of equations that could be used to find the weight (in kilograms) of each type of box.

(b). How much does each type of box weigh (in kilogrames)?​

Answer:

A. 5L + 3S = 135

7L + 9S = 255

B. Each small box weighs 13.75 kg

Each large box weighs 18.75 kg

Step-by-step explanation:

Part A:

Weight of each large box = L

Weight of each small box = S

✔️First Delivery:

Weight of 5 large boxes = 5L

Weight of 3 small boxes = 3S

Total weight = 135 kg

Equation that represents this would be:

5L + 3S = 135 ----› Eqn. 1.

✔️ Second Delivery:

Weight of 7 large boxes = 7L

Weight of 9 small boxes = 9S

Total weight = 255 kg

Equation that represents this would be:

7L + 9S = 255 ----› Eqn. 2

✔️System of equations would be:

5L + 3S = 135

7L + 9S = 255

Part B:

To find how much each box type weigh, solve simultaneously to find L and S.

5L + 3S = 135 ----› × 7

7L + 9S = 255 ----› × 5

35L + 21S = 945

35L + 45S = 1,275

Substraction

-24S = -330

Divide both sides by -24

S = 13.75

Each small box weighs 13.75 kg

Substitute S = 13.75 in eqn. 1 to solve for L

5L + 3(13.75) = 135

5L + 41.25 = 135

5L = 135 - 41.25 (subtraction property of equality)

5L = 93.75.

Divide both sides by 5

L = 18.75

Each large box weighs 18.75 kg
