Answer
The Cardinals' score is 82.
The Wolverines' score is 76.
Work Step by Step
Let $c$ be the score of the Cardinals.
The Wolverines' score is $c-6$.
$c+(c-6)=158$ $\longrightarrow$combine like terms
$2c-6=158$ $\longrightarrow$addition property
$2c-6+6=158+6$ $\longrightarrow$simplify
$2c=164$ $\longrightarrow$multiplication property
$2c\div2=164\div2$ $\longrightarrow$simplify
$c=82$
$c-6=82-6=76$
