Answer:
x=-2
Explanation:
you must get the variables on the same side first.
so 5x becomes negative 5x
those cancel each other out and now you have to do 12x - 5x. that gives you 7x. now you have 7x+11=-3. subtract 11 on both sides. -3-11= -14. now divide both sides by negative 7 and you have your answer.
