x+5 = 0
x+5 = 0
x+5 = 0
x+5 = 0 // - 5
x = -5
x in (-oo:-5) U (-5:+oo)
2/3 = 18/(x+5) // - 18/(x+5)
2/3-(18/(x+5)) = 0
2/3-18*(x+5)^-1 = 0
2/3-18/(x+5) = 0
(-18*3)/(3*(x+5))+(2*(x+5))/(3*(x+5)) = 0
2*(x+5)-18*3 = 0
2*x-44 = 0
(2*x-44)/(3*(x+5)) = 0
(2*x-44)/(3*(x+5)) = 0 // * 3*(x+5)
2*x-44 = 0
2*x-44 = 0 // + 44
2*x = 44 // : 2
x = 44/2
x = 22
