Merge similar items, that is, move the unknown to one side and the number to one side. In the process of change, there are several points to note:

For example: a-6=c

Move the bar C, it becomes a-c=6, and there is a minus sign in front of 6, which will change sign after moving.

Also, when you are new to the topic, simplify the topic first, and the number that can be reduced will be reduced.

In short: summary.

1。 Left solution left, right solution right.

2。 Transfer project: 1. If the symbols in front of the items containing X are the same, please make them smaller, but not larger.

2。 X's items are preceded by different symbols, so move-don't move+
