To solve this inequation you just need to isolate x ( put x in one side of the equation and its value in the other )
3 + 2/5x >= 17 - x
Subtract 3 in both sides of the equation to send 3 to the right side :
3 - 3 + 2/5x >= 17 - 3 - x
2/5x >= 14 - x
Add x in both sides of the equation to shift -x to the left side :
2/5 x + x >= 14
7/5x >= 14
Multiply both sides by 5 to send the /5 to the other side :
7/5x × 5 >= 14 × 5
7x >= 70
Divide both side by 7 to isolate x :
7/7x >= 70/7
x >= 70/7
x >= 10
