Question

If p = 10 - 3y, work out p when =-10

Answer 1

Hello.

Plug in the value of p:

$\mathrm{-10=10-3y}$

Now, all we have to do is solve the equation for y.

First, let's add 10 to both sides:

$\mathrm{-10+10=10+10-3y}$

$\mathrm{0=20-3y}$

Now, add 3y to both sides:

$\mathrm{3y=20}$

Divide both sides by 3:

$\Large\boxed{y=\frac{20}{3} }$

I hope it helps.

Have a nice day.
