Answer:
y = 5
Step-by-step explanation:
3y - 6y + 18= 8 + 3y - 20
in order to simplify this expression we need to consider the positive and negative signs carefully and diligently collect the like terms.
3y - 6y + 18= 8 + 3y - 20
3y -6y + 18 +20 = 8 + 3y
3y - 6y + 38 -8 = 3y
38-8 = 3y -3y + 6y
30 = 6y
divide both sides by 6
30/6 = 6y/6
5 = y
therefore y = 5
