Question

Solve for w. 5w + 9z = 2z + 3w A)w =-7/2 z B)w = -2/7z C) w = –2z D) w = –7z

Answer 1

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

Answer 2

Answer: The correct option is

(A)
`w=-(7)/(2)z.`

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

`5w+9z=2z+3w~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)`

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

From equation (i), we have

`5w+9z=2z+3w\\\\\Rightarrow 5w-3w=2z-9z\\\\\Rightarrow 2w=-7z\\\\\Rightarrow w=-(7)/(2)z.`

Thus, the required solution for w is
`w=-(7)/(2)z.`

Option (A) is CORRECT.
