according to the test I was working on, none of these are the right answer. x = (z+y)/y ,x=(z/y)+1 , z(y-1)

y(x-1) = z
(x-1) = z / y
x = ((z/y)+1)
the middle one.

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

the answer is x=z/y + 1

y(x-1) = z
x-1 = z/y
x = z/y + 1, I get the second choice.

are you sure it's not x=1+z/y? is there something else to the question?

y(x-1) = z
You have to distribute the y
yx - 1y = z
Add 1y to both sides and divide by y
yx - 1y + 1y = z + 1y
yx = z + 1y
x = (z+ y) / y
