Substitution

We want to find $\dfrac{ \alpha \cdot \beta }{ \theta }$ . We know that $\theta = 5$ , so we can switch these two values around. We can also do this with $\alpha$ and $\beta$ . So we switch in all of the numbers instead of the symbols (greek letters). We get $\dfrac{3 \cdot 4}{5} = \dfrac{12}{5}$ , which is the answer.
