n=-12
Answer:
x=1
Step-by-step explanation:
So, first you make sure to multiply the parenthesis by the negative so then it would be,
-x-3=2x-6
Then you add the -3 from the right to the other side
so, -x=2x-3
Then you want all the X variables to one side so you subtract the 2x to both sides.
so, -3x=-3
divide both by -3
x=1
When a () is right next to a number such as the problem you have it means to multiply. so 77 times -1 equals -77. so i'm not sure why -77 isn't one of your answer choices. maybe you mistyped something?
