Solving for x in the Equation (x-y)/x = z
This article will guide you through the steps of solving for x in the equation (x-y)/x = z.
Understanding the Equation
The equation (x-y)/x = z represents a relationship between three variables:
- x: The unknown variable we want to solve for.
- y: A known constant.
- z: A known constant.
Solving for x
Let's break down the process of solving for x:
-
Multiply both sides by x: This eliminates the fraction on the left side. (x-y)/x * x = z * x This simplifies to: x - y = zx
-
Subtract zx from both sides: This isolates the x terms on one side of the equation. x - y - zx = zx - zx This simplifies to: x - y - zx = 0
-
Factor out x: This allows us to combine the x terms. x(1 - z) - y = 0
-
Add y to both sides: This moves the y term to the right side. x(1 - z) = y
-
Divide both sides by (1 - z): This isolates x on the left side. x = y / (1 - z)
Final Solution
Therefore, the solution for x in the equation (x-y)/x = z is x = y / (1 - z).
Important Note:
It's important to note that the solution is only valid if (1 - z) ≠ 0. If (1 - z) = 0, then the equation becomes undefined, and there is no solution for x.
