y(x - 1) = z
First, divide both sides by y
(x - 1) = z / y
Now add 1 to both sides
x = (z / y) + 1

Usually when the question asks, what is x or what is something? It simply means you have to express that "something" in terms of the other things. So in this case, we're supposed to make x the subject of the equation.
y(x-1) = z
Expand the terms on the left of the equation:
yx-y = z
Add y to both sides of the equation:
yx = z + y
Divide both sides of the equation by y:
x = (z+y)/y (ANS)
There! You've now made x the subject of the equation.
Hope that helps you in explaining to your daughter how to solve the problem.
Cheers! =)

x= Z/ Y +1 OR YOU can say Z+Y/ Y

x - 1 = z / y
x = 1 + ( z / y )

x usually stands for the unknown, what is y & z doing here?
If this is the only function, to Slove the x, you have to give the value of y & z. just put the value of the y& z in this equation: x=z/y +1
Or you have other 2 sets of functions, then we can solve the value of x,y,&z

X is the 24th letter of the Alphabet. Let's keep it that way.

y(x-1) = z
yx - y = z
yx = z + y
x = z/y + y/y
x = z/y + 1 (Ans.)
