Systems where at least one equation is nonlinear (e.g., x² + y²=25 and x+y=7) require specialized approaches. You might solve for one variable, then substitute into the nonlinear equation, or use geometry (a line intersecting a circle) for interpretation. For instance, x+y=7 → y=7–x. Substituting into x²+(7–x)²=25 yields solutions for x. Nonlinear systems appear in conic section intersections, optimization problems, or advanced modeling tasks. Mastering them fosters a robust capacity to handle polynomial relationships and design solutions that go beyond straight lines.
