SOLUTION: (3x-4)/x<=(-2) The answer appears to be x<=4/5 but how do you prove that x must also greater than 0?

Question 133651: (3x-4)/x<=(-2)
The answer appears to be x<=4/5 but how do you prove that x must also greater than 0?

(3x-4)/x<=-2
x(3x-4)/x<=-2x
3x-4<=-2x
3x+2x-4+4<=-2x+2x+4
5x<=4
5x/5=4/5
x<=4/5
x cannot be 0 because in the original equation there would be division by 0 which is not allowed. x cannot be less than 0 because, as you can see from the graph below y>0 when x<0
So, X(0, 4/5]
or 0 .
