pls mark me as brainliest if you are satisficed
Step-by-step explanation:
25 - 4x < 16
25 -16 < 4x
9 < 4x
4x > 9
x > 9/4
x > 2.25
But here 2.25 is not an integer
x > 2.25 means x may be 3, 4, 5 and so on
Solution set { 3, 4, 5, 6.}
In these the least number is 3.
Therefore the smallest value of integer for x is 3
