### Changing the Subject of an Expression

Ex. 0:

y

=

(19x + 15)

(19x + -6)

=>

x

=

(15 - -6y)

(19y - 19)

Ex. 1:

y

=

(16x + -13)

(-10x + -6)

=>

x

=

(-13 - -6y)

(-10y - 16)

Ex. 2:

y

=

(14x + 9)

(-2x + 11)

=>

x

=

(9 - 11y)

(-2y - 14)

Ex. 3:

y

=

(11x + 3)

(18x + 3)

=>

x

=

(3 - 3y)

(18y - 11)

Ex. 4:

y

=

(9x + 14)

(18x + -6)

=>

x

=

(14 - -6y)

(18y - 9)

Ex. 5:

y

=

(-1x + 18)

(-5x + -1)

=>

x

=

(18 - -1y)

(-5y - -1)

Ex. 6:

y

=

(0x + -6)

(-5x + -12)

=>

x

=

(-6 - -12y)

(-5y - 0)

Ex. 7:

y

=

(-5x + -8)

(-15x + -5)

=>

x

=

(-8 - -5y)

(-15y - -5)

Ex. 8:

y

=

(-12x + -15)

(8x + -16)

=>

x

=

(-15 - -16y)

(8y - -12)

Ex. 9:

y

=

(-9x + 18)

(-2x + -14)

=>

x

=

(18 - -14y)

(-2y - -9)
