In solving the equation, the term should be shifted according to ()

Adding (or subtracting) the same number or the same integral on both sides of the equation is equivalent to changing the sign of some terms in the equation and moving them from one side of the equation to the other. This deformation is called term shifting. Note: "term shifting" refers to moving a term of the equation from the left side of the equal sign to the right or from the right to the left, When we want to move a term on the left (such as x) to the right, we actually subtract the term (x) from the left. According to the same solution principle, we must also subtract the term on the right, and then according to the subtraction rule, The opposite number of this term (x) must be added to the right side. Therefore, after the left term (x) is subtracted (from existing to nonexistent), the opposite number of this term (from nonexistent to existing) will appear on the right side. It gives people the feeling that the left term changes the sign and moves to the right side. It is the same principle to move some terms on the right side of the equation to the left side. This is term shifting
In solving the equation, the shift term should be changed according to the subtraction rule
