  1. 1Linear Equations in Two VariablesA masterclass in balancing acts: where two lines either cross paths perfectly, run away together forever, or realize they were the exact same line all along.
  2. 2Algebraic Method 1: The Substitution MethodIt’s essentially mathematical identity theft where you isolate one variable just to force its partner to do all the heavy lifting in the next equation.
  3. 3Algebraic Method 2: The Elimination MethodThe mathematical equivalent of 'this town ain't big enough for the both of us', where we aggressively delete one variable just to make the other one confess its value.
  4. 4Chapter Summary and PracticeGraphs and algebra join forces to settle pairs of equations from every angle.
