Form:

Connect equal formulas (or numbers expressed in letters) with "=".

Equations are divided into equations with unknowns and equations without unknowns.

For example:

X+1= 3-an equation with unknowns;

2+1= 3-an equation without unknowns.

It should be noted that some equations with unknowns have no solutions, but they still have no solutions, such as x+1= x-x.
