Leto [7]3 years ago
4 0

Answer:

The given equation having only one solution i.e., "w = 3". A further explanation is provided below.

Step-by-step explanation:

The given equation is:

⇒ 9(w-9)-2=-7w+7(w-8)

By opening the brackets, we get

⇒ 9w-81-2=-7w+7w-56

⇒ 9w-83=-56

On adding "83" both sides, we get

⇒ 9w-83+83=-56+83

⇒                 9w=27

⇒                   w=\frac{27}{9}

⇒                       =3
