Answer:

A

Step-by-step explanation:

Multiply both sides by 3

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

Remove the brackets.

3y - 9 = 2x+ 12                          Subtract 3y from both sides

- 9 = 2x - 3y + 12                       Subtract 12 from both sides

-9 - 12 = 2x - 3y                         Combine like terms

-21 = 2x - 3y                               Switch Sides

2x - 3y = - 12
