Short Answer

Expert verified

On simplifying the given expression, we get $6 w + 19 x^{2} y$

Step by step solution

Step 1. Given information

$\begin{array}{l} Thegivenexpressionis \\ - 12 w + 18 w + 7 x^{2} y - (- 12 x^{2} y) \\ Wehavetoaddorsubtractthegivenexpressionasapplicable. \end{array}$

Step 2. Simplify

$\begin{array}{l} Considerthegivenexpression \\ \Rightarrow - 12 w + 18 w + 7 x^{2} y - (- 12 x^{2} y) = (- 12 + 18) w + 7 x^{2} y + 12 x^{2} y \\ = 6 w + (7 + 12) x^{2} y \\ = 6 w + 19 x^{2} y \end{array}$
