x/1.5-x <= 0
0-0.33333333*x <= 0 // - 0
-0.33333333*x <= 0 // : -0.33333333
x >= 0/(-0.33333333)
x >= 0
x in (-oo:0)
-783.085 = ln(x/1.5-x) // - ln(x/1.5-x)
-ln(x/1.5-x)-783.085 = 0
-ln(x/1.5-x)-783.085 = 0 // + 783.085
-ln(x/1.5-x) = 783.085
-ln(x/1.5-x) = 783.085 // * -1
ln(x/1.5-x) = ln(e^-783.085)
x/1.5-x = e^-783.085
x/1.5-x-e^-783.085 = 0
-0.33333333*x = 0 // : -0.33333333
x = 0
x in { 0}
x belongs to the empty set
