9*x-5 = 0
9*x-5 = 0
9*x-5 = 0 // + 5
9*x = 5 // : 9
x = 5/9
x in (-oo:5/9) U (5/9:+oo)
105/(9*x-5) = 7 // - 7
105/(9*x-5)-7 = 0
105/(9*x-5)+(-7*(9*x-5))/(9*x-5) = 0
105-7*(9*x-5) = 0
140-63*x = 0
(140-63*x)/(9*x-5) = 0
(140-63*x)/(9*x-5) = 0 // * 9*x-5
140-63*x = 0
140-63*x = 0 // - 140
-63*x = -140 // : -63
x = -140/(-63)
