Answer:
x=-5
Step-by-step explanation:
3x+12= -3
-12 -12
(subtract 12 from both sides because you want the variable by itself)
3x= -15
(divide by 3 so you can get x completely by itself)
x= -5 (final answer)
x = -5
i took algebra a couple years ago :)
y-7/ 12y+3
x=-17
subtract 6 from each side and simplify and you'll get -17
