The equation 9(w-3) = -81 is solved in several steps below. For each step, choose the reason that best justifies it.​

For this case we have the following equation:

9 (w + 7) = 279(w+7)=27

To solve we follow the steps below:

We apply Distributive Property to the terms of parentheses:

9w + 63 = 279w+63=27

We apply Subtraction Property of equality by subtracting 63 from both sides of the equation:

\begin{gathered}9w + 63-63 = 27-63\\9w = -36\end{gathered}

9w+63−63=27−63

9w=−36

We apply Division Property of equality by dividing by 9 on both sides of the equation:

\frac {9w} {9} = \frac {-36} {9}

9

9w

=

9

−36

simplifiying

w = -4

w = -4w=−4

mean, 40.6
