The sum of number is at least 14 means the sum is either equal to 14 or greater then 14. So,

According to the question,

5x + 2x ≥ 14
= 7x ≥ 14
= x ≥ 14 / 7
= x ≥ 2

5x + 2x = AT LEAST 14
Which means 7x is at least 14
So if we divide both sides by 7
x is at least 2
which means it is 2 at its lowest value but could also be higher
-> we write this as greater than or equal to 2

x ≥ 2
