Answer:
.
Step-by-step explanation:

We need to find the factors of given equation;
Solution:
On Solving the above equation we get;
Now First we will take common factor from first 2 terms which is
we get;

Now we will take the common factor from the last 2 terms which is 3 we get;

Here we get 2 terms in which
is common factor.

Hence After factorizing the given equation we get
.

Step-by-step explanation:
<u><em>I'm going to assume that these photocopies are proportional in relations to each other.</em></u>
If they're proportional, you can set up two proportions:

And cross-multiply:

Then solved for x and y:
