Ex. 0:

y

=

(11x + -16)

(-2x + 7)

=>

x

=

(-16 - 7y)

(-2y - 11)

Ex. 1:

y

=

(-19x + -14)

(0x + -14)

=>

x

=

(-14 - -14y)

(0y - -19)

Ex. 2:

y

=

(-11x + -5)

(16x + 8)

=>

x

=

(-5 - 8y)

(16y - -11)

Ex. 3:

y

=

(-15x + -5)

(10x + 6)

=>

x

=

(-5 - 6y)

(10y - -15)

Ex. 4:

y

=

(-16x + -12)

(-12x + -19)

=>

x

=

(-12 - -19y)

(-12y - -16)

Ex. 5:

y

=

(-9x + 18)

(-3x + 6)

=>

x

=

(18 - 6y)

(-3y - -9)

Ex. 6:

y

=

(16x + -7)

(-17x + -7)

=>

x

=

(-7 - -7y)

(-17y - 16)

Ex. 7:

y

=

(5x + 10)

(3x + -3)

=>

x

=

(10 - -3y)

(3y - 5)

Ex. 8:

y

=

(13x + -19)

(-16x + 14)

=>

x

=

(-19 - 14y)

(-16y - 13)

Ex. 9:

y

=

(-14x + 4)

(19x + -5)

=>

x

=

(4 - -5y)

(19y - -14)
