Derivation
(-3*x-6)/6 == 6*x+4/3
⇒ algebra.equations.linear.balance.remove-div, factor=6-3*x-6 == 36*x+8
⇒ algebra.equations.linear.balance.var-right-plus, term=3*x-6 == 39*x+8
⇒ algebra.equations.linear.balance.con-left-minus, term=8-14 == 39*x
⇒ algebra.equations.linear.balance.scale-to-one, factor=39-14/39 == x
⇒ algebra.equations.linear.flipx == -14/39
