23.8 Model and solve one-step linear equations: ax=bax = b, xa=b\frac{x}{a} = b

Model and solve one-step linear equations: ax=bax = b, xa=b\frac{x}{a} = b

Linear equations which can be solved with a single operation are called one-step linear equations. In this section, we will try to solve one-step linear equations represented in diagrams and in equation form.
