Model and solve onestep linear equations: $ax = b$, $\frac{x}{a} = b$
Model and solve onestep linear equations: $ax = b$, $\frac{x}{a} = b$
Linear equations which can be solved with a single operation are called onestep linear equations. In this section, we will try to solve onestep linear equations represented in diagrams and in equation form.
