Answer :
[tex]5(9-3)=9w-5*3 \\\\ 5*6=9w-15 \\\\ 30=9w-15 \\\\ 30+15=9w \\\\ 45=9w \ |:9 \\\\ \boxed{w=5}[/tex]
5 (9 - 3) = w × 9 - 5 × 3 :First, distribute on the left side
45 - 15 = w × 9 - 5 × 3 :Then, take 45 - 15 on the left side and - 5 × 3 (Because of PEMDAS)
30 = w × 9 - 15 :Next, take 9 - 15
(30 = w × -6) ÷ -6 :Then, divide the equation by -6.
-5 = w
45 - 15 = w × 9 - 5 × 3 :Then, take 45 - 15 on the left side and - 5 × 3 (Because of PEMDAS)
30 = w × 9 - 15 :Next, take 9 - 15
(30 = w × -6) ÷ -6 :Then, divide the equation by -6.
-5 = w
