A 'system of equations' is not one problem. It is two truths tangled together. Your job is to rip them apart.

Weapon #1: Graphing. The elegant path. Graph both lines. The point where they intersect is the one, true answer.

Weapon #2: Substitution. The cunning path. Solve one equation for a variable, then substitute that into the other equation.

Weapon #3: Elimination. The brutal path. Add or subtract the two equations to make one variable completely disappear.

Your mission is to reduce two unknowns and two equations down to one unknown and one equation.

Once you have one variable, the other will fall easily. The first kill is the hardest.

This isn't just a math problem. It's a lesson in how to handle situations with multiple, conflicting constraints.

Choose your weapon based on the enemy's formation. Sometimes graphing is easy, sometimes elimination is best.

Know all three methods of attack, and no system can ever withstand your assault.

Two truths. One answer. Go find it. Annihilate the system.
