$\frac{x}{a} - 1 = \frac{y}{b}$

Step 1

Subtract $\frac{y}{b}$ from both sides of the equation.

$\frac{x}{a} - 1 - \frac{y}{b} = 0$

Step 2

Move all terms not containing $x$ to the right side of the equation.

Step 2.1

Add $1$ to both sides of the equation.

$\frac{x}{a} - \frac{y}{b} = 1$

Step 2.2

Add $\frac{y}{b}$ to both sides of the equation.

$\frac{x}{a} = 1 + \frac{y}{b}$

Step 3

Multiply both sides by $a$ .

$\frac{x}{a} a = (1 + \frac{y}{b}) a$
