Respuesta :

5w + 9z = 2z + 3w
5w = -7z + 3w
2w = -7z
w = -7/2 z
The answer is A. w = -7/2 z

Answer:  The correct option is

(A) [tex]w=-\dfrac{7}{2}z.[/tex]

Step-by-step explanation:  We are given to solve the following equation for w :

[tex]5w+9z=2z+3w~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

To solve the given equation for w, we must find the expression for w in terms of z.

From equation (i), we have

[tex]5w+9z=2z+3w\\\\\Rightarrow 5w-3w=2z-9z\\\\\Rightarrow 2w=-7z\\\\\Rightarrow w=-\dfrac{7}{2}z.[/tex]

Thus, the required solution for w is [tex]w=-\dfrac{7}{2}z.[/tex]

Option (A) is CORRECT.
