Question

Condition for system of equations to have no solution

Answer 1

Condition for Unique Solution to Linear Equations. A system of linear equations ax + by + c = 0 and dx + ey + g = 0 will have a unique solution if the two lines represented by the equations ax + by + c = 0 and dx + ey + g = 0 intersect at a point. ... Essentially, the slopes of the two lines should be different.
