### Instruction: Given that $\triangle+q=59$ and $(\triangle+q)+q=106$, what is the value of $\triangle$?### Response: I notice that the second equation involves adding another $q$ to both sides of the first equation.
So I can rewrite the second equation as $59+q=106$.
Solving for $q$, I get $q=106-59=47$.
Now I can plug this value of $q$ into the first equation and solve for $\triangle$.
I get $\triangle+47=59$, so $\triangle=59-47=12$.
