Octopus tentacles

Both octopuses have 112 tentacles. The pink octopus has 20 tentacles less than the yellow. How many tentacles does the pink octopus have, and how many does the yellow octopus have?

Final Answer:

a =  46
b =  66

Step-by-step explanation:

$$\begin{gathered} a+b=112 \\ a=b-20 \\ a+(a+20)=112 \\ 2a=92 \\ a=\frac{92}{2}=46 \\ a=46 \end{gathered}$$

$b=a+20=46+20=66$
