Question

Write the condition for unique solution​

Answer 1

Step-by-step explanation:

Explanatory Answer

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.

i.e., if the two lines are neither parallel nor coincident.

Essentially, the slopes of the two lines should be different.

What does that translate into?

Answer 2

Condition for unique solution is $\frac{a1}{a2} ≠ \frac{b1}{b2}$
