Chapter I : Linear Equations in two variables in two variables

Example 5. Find the solution of following system of equation such that :

Solution: Dividing both sides of the given equations by uv we get

Multiplying equation (2) by 2 and then subtracting equation (1) we get

Or, 15u = 15

u = 1

Putting u = 1 in equation on (1)

Or, 2/v = (7-3)/3

Or. 2/v = 4/3

Or, 4v = 6

Or, v = 6/4

Or, v = 3/2
