Answer: x = -1/3
Explanation:
so, this will be sort of like distribution. First distribute: 12-3x-13 = 0. 12-13 is equal to -1. So -3x - 1 = 0. Now to just get x variables, add 1 to both sides to cancel it out on the negative and add to the 0 side.
-3x = 1. Lastly, divide -3 to get x alone. Dividing it by both sides cancels out the left side and you are left with x = -1/3. Don’t forget: it’s a negative!
