### Changing the Subject of an Expression

Ex. 0:

y

=

(16x + 18)

(-18x + -16)

=>

x

=

(18 - -16y)

(-18y - 16)

Ex. 1:

y

=

(-14x + 10)

(-8x + -11)

=>

x

=

(10 - -11y)

(-8y - -14)

Ex. 2:

y

=

(-5x + -14)

(-5x + -18)

=>

x

=

(-14 - -18y)

(-5y - -5)

Ex. 3:

y

=

(-11x + -7)

(6x + -13)

=>

x

=

(-7 - -13y)

(6y - -11)

Ex. 4:

y

=

(2x + 4)

(6x + 12)

=>

x

=

(4 - 12y)

(6y - 2)

Ex. 5:

y

=

(-6x + 2)

(-10x + 14)

=>

x

=

(2 - 14y)

(-10y - -6)

Ex. 6:

y

=

(-18x + -13)

(-19x + -15)

=>

x

=

(-13 - -15y)

(-19y - -18)

Ex. 7:

y

=

(19x + 13)

(-19x + 15)

=>

x

=

(13 - 15y)

(-19y - 19)

Ex. 8:

y

=

(11x + -18)

(18x + 17)

=>

x

=

(-18 - 17y)

(18y - 11)

Ex. 9:

y

=

(11x + -9)

(-13x + -13)

=>

x

=

(-9 - -13y)

(-13y - 11)
