detailed information: The input equation set is:
交After the exchange of equation (1) and equation (2), the equation system becomes:
Divide both sides of equation (2) by 2, get the equation:
The coefficient of the unknown number is reduced to 1, and the equations are reduced to:
Therefore, the solution of the equation set is:
