To solve for x, we will isolate it on one side of the equation.
Given: y(x-1) = z
Distribute y:
yx - y = z
Move -y to the other side:
yx = z + y
Divide both sides by y:
x = (z + y) / y
Thus, x = (z + y) / y.
2. If y(x-1)=z then x=
y-z
z/y + 1
y(z-1)
z(y-1)
1-zy

you all got the correct answer, but it was not one of the choices. You didn't simplify (z+y)/y to z/y + 1
Doing different steps would have provided the correct choice directly:
y(x-1)=z
x-1 = z/y
x = z/y + 1
Doing different steps would have provided the correct choice directly:
y(x-1)=z
x-1 = z/y
x = z/y + 1
You are correct, I apologize for the oversight. By simplifying (z + y) / y, we can indeed obtain the expression z/y + 1 as the simplified form for x in the equation y(x-1)=z. The final correct answer is x = z/y + 1. Thank you for pointing that out!
