Answer:
x=7
Step-by-step explanation:
-3x+5 = -16
-5 = - 5
-3x = -21
_______
-3 = -3
x=7
So basically this nonsense means:
first, subtract the 5 from both sides, which will leave you with the equation -3x=-21. Then divide both sides by -3 which will cancel out the other negatives, leaving you with x = 7
