Solving Two-Step Equations
In Section 2-1 we learned to solve equations involving only one step:
addition/subtraction or multiplication/division.
Two-step equations require us to first add/subtract from both sides, then we
multiply/divide to isolate the variable (we reverse the order of
Process for solving two-step equations:
1. Add or subtract the constant term to get the variable term by itself
2. Multiply or divide the variable term to get a coefficient of 1.
