Short Answer

Expert verified

The result on solving is

$\begin{array}{l} a) 6 m \\ b) 23 y z^{2} \end{array}$

Step by step solution

Step 1. Given information

$\begin{array}{l} Thegivenexpressionsare \\ (a) - 3 m + 9 m \\ (b) 15 y z^{2} - (- 8 y z^{2}) \\ Wehavetoaddorsubtractthegivenexpressionsasapplicable. \end{array}$

Step 2. Solving part (a)

$\begin{array}{l} Considerthegivenexpression \\ \Rightarrow - 3 m + 9 m = (- 3 + 9) m \\ = 6 m \end{array}$

Step 3. Solving part (b)

$\begin{array}{l} Considerthegivenexpression \\ \Rightarrow 15 y z^{2} - (- 8 y z^{2}) = 15 y z^{2} + 8 y z^{2} \\ = (15 + 8) y z^{2} \\ = 23 y z^{2} \end{array}$
