Are you trying to figure out what's x?
Since z varies jointly as x and y, the value of z when x = 7 and y= 8 is; 112
According to the question, z varies jointly with X and y.
- In essence, the relationship between z, x and y can be written as;
z = kxy
- where k= constant of proportionality.
We therefore need to find k first, from the first set of values of z, ,x and y.
Then;
Consequently, the value of z when x = 7 and y = 8 is as follows;
z = 112.
