Answer:

Step-by-step explanation:
- To know the value that y takes according to the inequation
, we must do some algebra. - First of all, we divide both terms by (-3), wich would change the direction of the inequality, as follow:
(at this point you should remember that dividing or multiplying an inequation by anegative number changes the direction of the inequality).. - This means that
. Then,we just have to add both sides 4, which yields
. - Then
, which means that, if we divide both sides by 5, we obtain the value of y:
(in this case, the direction of inequality does not change because 5 is possitive).
Answer:
3) y = 2
Step-by-step explanation:
Step : 1
given 2 y-1 =3
Adding '1 ' on both sides, we get
2 y -1 +1 = 3+1
2 y = 4
dividing by '2' on both sides, we get

cancelling '2' on both sides, we get
y = 2
