From the text, we can extract the followed equation:
[tex]\text{length}=36\text{ + 2}\times(\text{wingspan)}[/tex]We know that the length is equal to 214 inches, so lets put this value in our equation:
[tex]\text{length}=36\text{ + 2}\times(\text{wingspan) }\Rightarrow\text{ 214}=36\text{ + 2}\times(\text{wingspan) }\Rightarrow\text{214 - 36}=\text{ 2}\times(\text{wingspan)}[/tex]Continuing our calculation, we have:
[tex]\text{178}=\text{2}\times(\text{wingspan) }\Rightarrow\text{ }\frac{\text{1}78}{2}=(\text{wingspan) }\Rightarrow\text{89}=(\text{wingspan)}[/tex]So our wingspan is 89 inches.
