Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.An employee at a company that assembles chandeliers is packing boxes for shipping. In the first box, he packed 4 small chandeliers and 2 large chandeliers, which weighed a total of 66 kilograms. In the second box, he packed 4 small chandeliers and 4 large chandeliers, which had a weight of 112 kilograms. Assuming the weight of the box isn't included in the shipping weight, how much does each size of chandelier weigh?Each small chandelier weighs _ kilograms and each large one weighs _ kilograms.
Q. Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.An employee at a company that assembles chandeliers is packing boxes for shipping. In the first box, he packed 4 small chandeliers and 2 large chandeliers, which weighed a total of 66 kilograms. In the second box, he packed 4 small chandeliers and 4 large chandeliers, which had a weight of 112 kilograms. Assuming the weight of the box isn't included in the shipping weight, how much does each size of chandelier weigh?Each small chandelier weighs _ kilograms and each large one weighs _ kilograms.
Denote weights: Let's denote the weight of each small chandelier as s and the weight of each large chandelier as l. The first box with 4 small chandeliers and 2 large chandeliers weighs a total of 66 kilograms, which gives us the equation 4s+2l=66.
First box equation: The second box with 4 small chandeliers and 4 large chandeliers weighs 112 kilograms, which gives us the equation 4s+4l=112.
Second box equation: We now have a system of two equations. To use elimination, we can subtract the first equation from the second equation to eliminate s. Subtracting 4s+2l=66 from 4s+4l=112 gives us 2l=46.
Elimination method: Dividing both sides of 2l=46 by 2 gives us l=23. This means each large chandelier weighs 23 kilograms.
Large chandelier weight: Now that we know the weight of each large chandelier, we can substitute l=23 into the first equation 4s+2l=66 to find the weight of each small chandelier. Substituting l gives us 4s+2(23)=66.
Substitute in first equation: Simplifying the equation 4s+46=66 by subtracting 46 from both sides gives us 4s=20.
Find small chandelier weight: Dividing both sides of 4s=20 by 4 gives us s=5. This means each small chandelier weighs 5 kilograms.
