Answer:
you have #5 correct and that is how I would do it.
you could also figure out the number of flowers and put 6 in each vase.
7x12= 84
84/6= 14.
I still think your way is best.

Comments:
We can see that as long as we add/subtract any value to both sides nothing happens: true statements remain true and false statements remain false. But if we multiply or divide by negative values, false statements become true and true statements become false. That why, when you multiply or divide an inequality by a negative number, you should also flip the inequality sign. For example, if we start with the true inequality

If we multiply both sides by -2 we have to flip the sign as well:

And the inequality will remain true.
The answer is : will be added by 5
3x +2y= 11 ----1
x -2 = -4y ---- 2
Equation 2 times by 3
3x -6 = -12y
Subracting 2-1
3x-6=-12y
3x-11=-2y
Leaving
5=-10y
y= -1/2
Hence
B. is the solution
PS, If you rate this as "Brainiest" that would be most appreciated
