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.
