For Wendy’s age you can’t do 30-6=24 and then for Zaviel’s you can do 24-6=18 so Wendy is 24 years old and Zaviel is 18 years old.
30-6=w
W-6=z
30-6=24(w)
24-6=18(z)

The distribution of the balls is an illustration of proportions, and 4 of the golf balls are yellow
<h3>How to determine the number of yellow golf balls?</h3>
The distribution of the balls are given as:
Total = 28
Yellow = 1/7
The number of yellow balls is given as:
Yellow = 1/7 * Total
This gives
Yellow = 1/7 * 28
Evaluate the product
Yellow = 4
Hence, 4 of the golf balls are yellow

X+y=7
x•y=-18
x+y=7
x=7-y
x•y=-18
(7-y)•y=-18
7y-y^2=-18
-y^2+7y+18=0
Y^2-7y-18=0
(y-9)(y+2)=0
y is either 9 or -2
x+y=7
x=7-y
X=7-9
X=-2
X•y=-18
9•(-2)=-18
-18=-18
There you go, y is 9 and x is -2
