How do you solve p=irt. show the step by steo solution.

P= IRT solve for T To solve for T, you must get T on it's own on one side of the equals sign, with all the other terms on the other side. IRT means that I and R are multiplied by T. To get rid of them we must do the opposite of multiply, which is divide. But because this is an equation, anything we do on one side of the equals sign, must be repeated on the other side. So if we divide the right side by IR, we must also divide the left side by IR

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
