Boxers = b
Spaniels = s
![b=s*4](https://tex.z-dn.net/?f=b%3Ds%2A4)
![s+b=30](https://tex.z-dn.net/?f=s%2Bb%3D30)
Now you have two equations - one that tells you the number of boxers in relation to spaniels and one telling you the number of each breed in relation to the total number of dogs. Solve using substitution.
![s+(4*s)=30 \\ 4s+s=30 \\ 5s=30 \\ s=6](https://tex.z-dn.net/?f=s%2B%284%2As%29%3D30%20%5C%5C%204s%2Bs%3D30%20%5C%5C%205s%3D30%20%5C%5C%20s%3D6)
There are
6 spaniels.

Step-by-step explanation:
1. The pin’s placement helps to make two drawings simultaneously. This is that while drawing an image a copy, which may vary in size, is created at the same time.
2. The pantograph relates to dilations and similarity due to the use of similar triangles that affect the scale of the second drawing.
3. The use of similar triangles illustrates the process of the pantograph because the ratio of similitude is set when determining where to place the pin. When a triangle is moved while tracing a line, along with the outline of the image, an enlarged/reduced version of the image is created by the other pantograph's end.
4. The pantograph is now obsolete and has been replaced by several different ways of producing duplicates such as photocopying, mass printing, and digital filing.
