Hi there !

3x + 12 = - 6x - 9

3x + 6x = - 12 - 9

9x = - 21

x = - 21⁽³/9

x = - 7/3

x = - 2  1/3

12x + 20 = 2x

12x - 2x = - 20

10x = - 20

x = - 20/10

x = - 2

Good luck !

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.
