Answer: 321q = z
This is the same as z = 321q
The term "product" means "result of multiplying two or more values"
For example, the product of 2 and 3 is 2*3 = 6
Writing 321q is the same as 321*q, but we often leave out the multiplication sign. You could say q*321, but convention usually has the number come first then the variable second. The 321 is the coefficient.
