Systems of Linear Equations

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

A system of linear equations is a set of equations sharing variables; a solution is one assignment satisfying every equation at once — graphically, the intersection point.

Show

x + y = 7 and x − y = 3 are both true only at (5, 2): one point on both lines.

Builds on

  • Nothing — this is a starting point.

Unlocks

  • Nothing yet depends on this.
