If x < 0, y > 0, and x + y = z, which statement about z is true?

Z is greater than zero because it equals 1 or more.

Step-by-step explanation:

X/Y/Z=1+

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

it would be 6xy and -16xy.
