Question
Solve the following inequation
2a + 3 ≤ 13, where a is a whole number
Solution
2a + 3 ≤ 13
Subtracting 3 from both the sides
2a + 3 – 3 ≤ 13 – 3
2a ≤ 10
Dividing both the side by 2
`(2"a")/2` ≤ `10/2`
a ≤ 5
Since the solutions belong to the set of whole numbers that are less than or equal to 5 we take the values of a as 0, 1, 2, 3, 4 and 5
