Solve the following linear inequations in R

12x < 50, when


i. x R


ii. x Z


iii. x N

Given 12x < 50




i. x R


When x is a real number, the solution of the given inequation is.


ii. x Z


As, when x is an integer, the maximum possible value of x is 4.


Thus, the solution of the given inequation is {…, –2, –1, 0, 1, 2, 3, 4}.


iii. x N


As, when x is a natural number, the maximum possible value of x is 4 and we know the natural numbers start from 1.


Thus, the solution of the given inequation is {1, 2, 3, 4}.
