    Yep. \[V = 380 \implies 380 = 20\sqrt{t+237}\]

    380=20 SQRT t + 273 107=20sqrt t (107/20)^2=t

    Usually each sentence will be giving you an equation or inequality that you can use. Just try to interpret the sentence into an equation, then take all the equations and try to find what they're looking for.
