Solution: 98-3x=

98-3x+3x=

98=3x=

3x 3=x=Analytical: Adding (or subtracting) the same number or the same integer on both sides of the equation is equivalent to moving some terms in the equation from one side of the equation to the other after changing the sign, and this deformation is called shifting terms. Note:

"Shift" refers to moving an term of an equation from the left to the right or from the right to the left. The shift is based on the law of subtraction: a-b = a+(-b), i.e. subtracting a number is equal to adding the opposite of the number.

When we want to move a term on the left (such as x) to the right, we actually subtract the term (x) on the left, and according to the principle of the same solution, we must also subtract this term from the right, and then according to the law of subtraction, the opposite number of this (x) must be added to the right, so after the left term (x) is subtracted (from there to nothing), his opposite number appears on the right (from nothing to nothing). It feels like the item on the left has changed the symbol and moved to the right. It's the same thing to move some of the terms on the right side of the equation to the left.

This is the move item.
