Question

The possible values of x are given by x−3≥2 . What is the least possible value of 5x ?

Answer 1

X has to be higher than 1. 5-3 is 2, which is equal to two but not greater than. X cannot be less than 1. To show this in an inequality:

x$\geq$1

Answer 2

$x-3\geq2 implies x \geq 3+2 hence x \geq 5$.

this means x has smallest value 5.

THE SMALLEST VALUE OF 5X will thus be 5 * 5 = 25
