Answer
The capacity of Michigan Stadium is 106201.
The capacity of Beaver Stadium is 107282.
Work Step by Step
Let $m$ be the capacity of Michigan Stadium.
The capacity of Beaver Stadium is $m+1081$.
$m+(m+1081)=213483$ $\longrightarrow$combine like terms
$2m+1081=213483$ $\longrightarrow$addition property
$2m+1081-1081=213483-1081$ $\longrightarrow$simplify
$2m=212402$ $\longrightarrow$multiplication property
$2m\div2=212402\div2$ $\longrightarrow$simplify
$m=106201$
$m+1081=106201+1081=107282$
