(Note that this equation would be undefined for )

Multiply both sides by x

Add 2x to both sides

Combine terms

Add -3 to both sides

Multiply both sides by

Note that we did not multiply by a negative quantity at any time, so the sense of the inequality (less than or equal) did not change. We also want to make sure that there are no values in the solution set that could cause the rational expression in the original equation to have a zero denominator. In this case we are safe because the only value that would be a problem is x = 0 but that is outside of the solution set interval

(x+3)/x<=-2 cross multiply.
x+3<=-2x
x+2x<=-3
3x<=-3
x<=-3/3
x<=-1 answer.
proof.
let x=-1.1
(-1.1+3)/-1.1<=-2
1.9/-1.1<=-2
-1.72<=-2
