Linear Equations in Two Variables
A linear equation in two variables has the form ax+by=c, and solving systems of such equations finds values satisfying multiple conditions.
Core concept
A linear equation in two variables, like 2x+3y=12, has infinitely many solutions, each represented as a point on a line when graphed.
How it works
A system of two linear equations can be solved using substitution (solving one variable, substituting into the other equation).
Why it matters
Elimination method solves systems by adding or subtracting equations to eliminate one variable, finding the value of the other.
Key detail
Graphically, the solution to a system of two linear equations is the point where their two lines intersect on a graph.
