Answer:
Step-by-step explanation:
[tex]r = \frac{4}{3} (p - q)[/tex]
Multiply through by 3 to eliminate the fraction
That's
[tex]3r = 4(p - q)[/tex]
Divide both sides by 4
[tex] \frac{3r}{4} = \frac{4(p - q)}{4} \\ p - q = \frac{3r}{4} [/tex]
Move q to the other side of the equation to make p stand alone
We have the final answer as
[tex]p = \frac{3r}{4} + q \\ [/tex]
Hope this helps you
