x in (-oo:+oo)
(3/7)*x-1 = (2/3)*(6*x-2) // - (2/3)*(6*x-2)
(3/7)*x-((2/3)*(6*x-2))-1 = 0
(-2/3)*(6*x-2)+(3/7)*x-1 = 0
(3*x)/7-2/3*(6*x-2)-1 = 0
(-2/3*7*(6*x-2))/7+(3*x)/7+(-1*7)/7 = 0
3*x-2/3*7*(6*x-2)-1*7 = 0
28/3-25*x-7 = 0
7/3-25*x = 0
(7/3-25*x)/7 = 0
(7/3-25*x)/7 = 0 // * 7
7/3-25*x = 0
7/3-25*x = 0 // - 7/3
-25*x = -7/3 // : -25
x = -7/3/(-25)
x = 7/75
x = 7/75
