For both problems, we can use the section formula.

1) P=\left(\frac{(1)(1)+(5)(-9)}{6}, \frac{(1)(8)+(5)(3)}{6} \right)=\boxed{\left(-\frac{22}{3}, \frac{23}{6} \right)}

2) Z=\left(\frac{(2)(7)+(1)(1)}{3}, \frac{((2)(5)+(1)(2)}{3} \right)=\boxed{(5, 4)}

<u>Flip the equation</u>

<u></u>24=3n---->3n=24<u></u>

<u></u>

<u>Divide both sides by 3</u>

<u></u>3n/3=24/3<u></u>

<u></u>24/3=8----> n=8<u></u>
