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
