Answer:
Well, Your best answer will be is
B. 2x-3y=12
C. -4(2x-3y) = -4(12).
First you have to multiply by 3
Which it give you 3y =2x -12 of the factor 2 3y = 2(x-6)
Then after that you subtract 2x of each sides.
Because, -2x+3y = -12
Then you must multiply by -1
Because,2x -3y = 12
Than you basically multiply by -4
Which that give you -4(2x - 3y) = -4(12)
Good Luck!
