3 * ( Y - 3 ) = X + 2 ; X ≠ - 2
3Y - 9 = X + 2
X = 3Y - 9 - 2
X = 3Y - 11
-----------------------------------
Y * ( 3Y - 11 ) + 3 * ( 3Y - 11 ) + 4Y = 0
3Y^2 - 11Y + 9Y - 33 + 4Y = 0
3Y^2 + 2Y - 33 = 0
D = 4 + 396 = 400 ; √ D = 20
Y1 = ( - 2 + 20 ) : 6 = 3
Y2 = ( - 22 ) : 6 = - 3 ( 2/3 )
--------------------------------------
X = 3Y - 11
X1 = 9 - 11 = - 2 ( не подходит )
X2 = 3 * ( 11/3 ) - 11 = 11 - 11 = 0
