Answer:
3x-12 is the simplififed answer
Step-by-step explanation:
the equation is almost already simplified. when you combine -8 and -4, which are like terms, you get 3x-12. because there are no more lie temrs in the equation, it can not be simplififed any further.
The ordered pair of the origin is (0,0)
Maybe try using Photomath it works for me. Good luck
