Extended data:

After solving the equation, it needs to be verified, and the values of the solved unknowns are substituted into the original equation to see if the two sides of the equation are equal. If they are equal, then the value obtained is the solution of the equation.

When solving an equation, x is not necessarily placed on the left side of the equation, or there are two x's in an equation, so it needs to be solved by simple calculation methods in mathematics. Some formulas have an X on the right, which can be simply calculated in a different position.
