Step-by-step explanation:
7-3x>=-1/2
-3x>=-1/2-7
-3x>=-(7+1/2)
-3x>=-15/2
3x<=15/2 ( sign of the operator reverses as both sides are divided by -1)
x<=15/(2*3)
x<=15/6=5/2=2.5
that is the answer to the Inequation
but now , replacement set=W(set of whole numbers is represented by W)
so the solution set
(in roster form)
{0,1}
or in set builder form
{x:x x<2.5 , x(plz use belongs to symbol here)W}
thanks and mark as brainliest
