Solution for 1/3*-1/9y=3 equation:
y in (-oo:+oo)

((-1*(1/3))/9)*y = 3 // - 3

((-1*(1/3))/9)*y-3 = 0

((-1/3)/9)*y-3 = 0

-1/27*y-3 = 0 // + 3

-1/27*y = 3 // : -1/27

y = 3/(-1/27)

y = -81

y = -81Solution for 2/3*1/5y=9 equation:
y in (-oo:+oo)

((1*(2/3))/5)*y = 9 // - 9

((1*(2/3))/5)*y-9 = 0

((2/3)/5)*y-9 = 0

2/15*y-9 = 0 // + 9

2/15*y = 9 // : 2/15

y = 9/2/15

y = 135/2

y = 135/2
