xp + yp = z
You are solving for p :)
So, in order to find the value of p, you must get p to it's own side, and isolate it.
Since there are two "p's," you could change "xp + yp" to "p(x + y).
p(x + y) = z
Then, we must divide both sides by x + y
p(x + y) ÷ x + y = z ÷ x + y
Simplify.
p = z/x + y
[tex]p = \frac{z}{x+y} [/tex]\
