# Two-step equations

## By Khan Academy

Here's how we solve a two step equation. It begins with the concept of equality: what we do to one side of the equation must be done to the other.  # Two-step equations

## By Khan Academy

Solve the equation by isolating the term with numerator x.  # Two-step equations

## By Khan Academy

Let's practice some two step equations, some of which require merging terms and using the distributive property.  # Two-step equations
