Final answer:
Graphical solutions involve plotting linear equations to find intersections for two unknowns.
Explanation:
Graphical solutions involve plotting linear equations on graph paper, where the solution is where the lines intersect. This method is practical for systems of two unknowns due to ease of graphing, but complex for systems with more variables.
The graph of a linear equation like y = a + bx is a straight line, providing a visual representation of the relationship between variables in the system.
For systems with more equations, LU decomposition can be used to solve the equations in a general form, allowing for efficient computation of solutions.
