Work Step by Step

Let $c$ be the score of the Cardinals. The Huskies' score is $c+33$. $c+(c+33)=153$ $\longrightarrow$combine like terms $2c+33=153$ $\longrightarrow$addition property $2c+33-33=153-33$ $\longrightarrow$simplify $2c=120$ $\longrightarrow$multiplication property $2c\div2=120\div2$ $\longrightarrow$simplify $c=60$ $c+33=60+33=93$
