Can someone please help I need a clear explanation on how to solve this equation.
nikitadnepr [17]
B = amount of students who chose Bulldog

n = amount of students who chose lion

t = amount of students who chose tiger

so.. "t" chose tiger, ok

"<span>Four times as many students chose Bulldog as chose Tiger"
namely, if "t" chose tiger, then 4 times that many chose Bulldog, thus

b = 4t

"</span><span>Twice as many students chose Lion as chose Tiger"
namely, if "t" students chose tiger, twice as many chose lion

n = 2t

now, we know a total of 273 students were surveyed, thus

</span>\bf \begin{cases}&#10;b+n+t=273\\&#10;\boxed{4t}+\boxed{2t}+t=273&#10;\end{cases}&#10;\\\\\\&#10;7t=273\implies t=\cfrac{273}{7}\impliedby \textit{that many chose \underline{tiger}}<span>
