Answer

a) n>6

b) -4,-3,-2,-1,0,1

   

Step-by-step explanation:

a) 15n>12n+18

   subtracting 12n from both the sides

   15n-12n > 12n + 18 - 12n

   3n>18----(1)

  dividing equation 1 by 3

  3n/3 > 18/3

  Ans : n>6

b) -2<n+3<=4

    taking -2<n+3

  subtracting 3 from both the sides

 -2-3<n+3-3

 -5<n ----(1)

 taking n+3<=4

 subtracting 3 from both the sides

 n+3-3<=4-3

 n<=1----(2)

 combining eq. 1 and 2

 -5<n<=1

 therefore the values of n are : -4,-3,-2,-1,0,1
