Answer:

   r = P -t -s

Step-by-step explanation:

This is a one-step linear equation in r. Subtract the terms that don't contain r:

  P = r + t + s . . . . . . . . . .  given

The terms on the right that don't include r are (t+s). We want to subtract that to get r by itself.

  P -(t+s) = r +(t+s) -(t+s) . . . subtract (t+s)

  P -t -s = r . . . . . . . . . . . . . . simplify

  r = P - t - s

given y left parenthesis z right parenthesis equals space fraction numerator z squared minus 1 over denominator z left parenthes
aivan3 [116]

The simplification of the given algebraic expression is;

yz = (z + 1)/z(z - 1)

<h3>How to simplify algebraic expressions?</h3>

We are given y left parenthesis z right parenthesis which is expressed as; yz

Now, we are given the algebraic expression that yz equals space fraction numerator z squared minus 1 over denominator z left parenthesis z minus 1 right parenthesis squared end fraction

z squared minus 1 over denominator z left parenthesis z minus 1 right parenthesis squared end fraction is expressed as; (z² - 1)/z(z - 1)²

Thus, our main expression is;

yz = (z² - 1)/z(z - 1)²

Factorizing the numerator and denominator gives;

yz = (z + 1)(z - 1)/z(z - 1)(z - 1)

(z - 1) is common to both numerator and denominator and as such, we now have;

yz = (z + 1)/z(z - 1)
