"Use the variable v to represent Victor's height"
So, from that, we know we're writing a function in terms of v.
"117 is the product of Victor's height (v) and 9".
If we remember that the product is multiplication, and we see that the word "is" is often used to mean "equals", we can get:
117 = product of Victor's height and 9
117 = v * 9
117 = 9v
That there is your answer. If we then wanted to take this beyond the scope of the problem, we could solve for what Victor's height would be, by solving for v.
117 = 9v
117/9 = (9v)/9
117/9 = v
13 = v
So, we get that Victor's height is 13.
