2X=6

Then this equation belongs to a linear equation, and the solution is very simple. Can only be used on both sides at the same time.

÷2

(This step is called moving items. )

Then this equation becomes-

x = 6 \2

So X=2, this is the solution of the equation.

So we can know that x y = w.

If x is unknown here and others are known, let's solve it. We just need to move y to the right. So we can know what x equals.

The way to move is to get out of both known unknowns at the same time.

If it is a complex one-dimensional linear equation, then step by step.
