Step 2.3.1.2.2.1

Factor $2$ out of $2$ .

$y = - 3 + \frac{2 (- x)}{2 (1)}$

$3 x - 2 y = 11$

Step 2.3.1.2.2.2

Cancel the common factor.

$y = - 3 + \frac{2 (- x)}{2 \cdot 1}$

$3 x - 2 y = 11$

Step 2.3.1.2.2.3

$y = - 3 + \frac{- x}{1}$

$3 x - 2 y = 11$

Step 2.3.1.2.2.4

Divide $- x$ by $1$ .

$y = - 3 - x$

$3 x - 2 y = 11$

$y = - 3 - x$

$3 x - 2 y = 11$

$y = - 3 - x$

$3 x - 2 y = 11$

$y = - 3 - x$

$3 x - 2 y = 11$

$y = - 3 - x$

$3 x - 2 y = 11$

$y = - 3 - x$

$3 x - 2 y = 11$

Step 3

Subtract $3 x$ from both sides of the equation.

$- 2 y = 11 - 3 x$

$y = - 3 - x$

Step 4.3.1.1

Move the negative in front of the fraction.

$y = - \frac{11}{2} + \frac{- 3 x}{- 2}$

$y = - 3 - x$

Step 4.3.1.2

Dividing two negative values results in a positive value.

$y = - \frac{11}{2} + \frac{3 x}{2}$

$y = - 3 - x$

$y = - \frac{11}{2} + \frac{3 x}{2}$

$y = - 3 - x$

$y = - \frac{11}{2} + \frac{3 x}{2}$
