Question

How do you solve the equation for w: `wxy + z + 1 = 6`?

Answer 1

Provided neither `x` nor `y` are `0`
`color(white)("XXXX")` `w= (5-z)/(xy)`

Explanation:

If `wxy+z+1 = 6`
then
`color(white)("XXXX")` `wxy +z = 5`

`color(white)("XXXX")` `wxy = 5-z`
and if `xy!=0`
`color(white)("XXXX")` `w=(5-z)/(xy)`
