Answer:
189 = W
Step-by-step explanation:
-21 = -w/9
-21 * 9 = -w/9 * 9
The denominator and numerator in the right side cancel out.
-189 = -w
189 = w
w = 189
[tex]\large \textsf{$-\dfrac{w}{9}$} = -21 \implies \normalsize \textsf{multiply both sides by -9}\\\\\\\large \textsf{$(-9)-\dfrac{w}{9} = -21(-9)$}\\\\\\\large \text{w = 189}[/tex]
Hope this helps!
