Question

At the dog show, there are 4 times as many boxers as spaniels. If there are a total of 30 dogs,how many are spaniels?

Answer 1

$x-the \ number \ of \ the \ spaniels \\ 4x-the \ number \ of \ the \ boxers \\\\ x+4x=30 \\\\ 5x=30 \\\\ \boxed{x=\frac{30}{5}=6 spaniels} \\\\ 6*4\to\boxed{24 \ boxers}$
