Answer:

Step-by-step explanation:
When y varies jointly as x and z, the equation is written ...
y = k·x·z
Here, the joint variation is not with z, but with z². There is also an inverse variation with w, so the entire relation is ...
y = k·x·z²/w
We want to find the value of k for the given values of the variables. So, we can solve for k to get ...

Then the equation of variation is ...

<span>−3|x − 3| = −6
</span><span> |x − 3| = 2
x - 3 = 2
x = 5
-(x - 3) = 2
-x + 3 = 2
-x = -1
x = 1
answer
x = 1 and x =5</span>
