We solve an equation by working out the value for one letter. To solve an equation we use the inverse operations to undo the equation. STEP 5 - You’ve found the answer x = 2. Always remember to ...

We have looked at how to solve equations with one unknown value, but what happens when there are two unknown values? An equation with two unknown values will have infinitely many solutions.

and to demonstrate that the general equation of any degree higher than the fourth cannot be solved by an algebraic formula. It is strange that no reference is given to the work of Kronecker and ...
