A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. Each

Ostrovityanka [42]

Answer:

There were 7 small boxes and 14 large boxes shipped.

Step-by-step explanation:

This problem may be solved by a system of equations:

I am going to say that:

x is the number of small boxes used

y is the number of large boxes used

There were twice as many large boxes shipped as small boxes shipped

This means that $y = 2x$

Each small box of paper weighs 45 pounds and each large box of paper weighs 80 pounds. The total weight of all boxes was 1435 pounds.

This means that $45x + 80y = 1435$

So we have to solve the following system:

$y = 2x$

$45x + 80y = 1435$

$45x + 80(2x) = 1435$

$205x = 1435$

$x = \frac{1435}{205}$

$x = 7$

$y = 2x = 2(7) = 14$

There were 7 small boxes and 14 large boxes shipped.

How do you do this system using the equal values method?

Pavel [41]

To use the equal values method, we want to get both of these equations equal to the same thing, and then set them equal to each other. To do this, let's solve both for x:
$x+2y=14$
$x=14-2y$

For the second equation:
$-x+3y=26$
$-x=26-3y$
$x=3y-26$

Then if we set these two equal to each other:
$3y-26=14-2y$
$5y-26=14$
$5y=40$
$y=8$

Then we take this y value and plug it back into either of our starting equations. I'll use the first one as an example:
$x+2(8)=14$

Now just solve for x and you'll have your solution.
