How many solutions does this equation have?

Leto [7]

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

⇒ $9w-83+83=-56+83$

⇒ $9w=27$

⇒ $w=\frac{27}{9}$

⇒ $=3$

I don’t understand. and someone please help?

givi [52]

Solution:

Note that:

6x + 26 = 92 (Vertically opposite angle)
92 + 92 + z + z = 360

Finding x.

6x + 26 = 92
=> 6x = 92 - 26
=> 6x = 66
=> x = 11

Finding z.

92 + 92 + z + z = 360
=> 184 + 2z = 360
=> 2z = 360 - 184
=> 2z = 176
=> z = 176/2 = 88
