Description
Solve a linear equation using only balance rules.
Derivation
3/4*x-x+1 == 3+5/2*x-5/2
⇒ algebra.equations.linear.balance.remove-div, factor=43*x-4*x+4 == 12+10*x-10
⇒ algebra.equations.linear.balance.collect-x+4 == 2+10*x
⇒ algebra.equations.linear.balance.var-right-plus, term=x4 == 2+11*x
⇒ algebra.equations.linear.balance.con-left-minus, term=22 == 11*x
⇒ algebra.equations.linear.balance.scale-to-one, factor=112/11 == x
⇒ algebra.equations.linear.flipx == 2/11
