Step 1.1

Replace all occurrences of $x$ in $- 3 x + 3 y = 6$ with $y + 2$ .

$- 3 (y + 2) + 3 y = 6$

$x = y + 2$

Step 1.2.1.1.1

Apply the distributive property.

$- 3 y - 3 \cdot 2 + 3 y = 6$

$x = y + 2$

Step 1.2.1.1.2

Multiply $- 3$ by $2$ .

$- 3 y - 6 + 3 y = 6$

$x = y + 2$

$- 3 y - 6 + 3 y = 6$

$x = y + 2$

Step 1.2.1.2

Combine the opposite terms in $- 3 y - 6 + 3 y$ .

Step 1.2.1.2.1

Add $- 3 y$ and $3 y$ .

$0 - 6 = 6$

$x = y + 2$

Step 1.2.1.2.2

Subtract $6$ from $0$ .

$- 6 = 6$

$x = y + 2$

$- 6 = 6$

$x = y + 2$

$- 6 = 6$

$x = y + 2$

$- 6 = 6$

$x = y + 2$

$- 6 = 6$

$x = y + 2$

Step 2

Since $- 6 = 6$ is not true, there is no solution.
