Solve the following pair of linear equations graphically and shade the region bounded by these lines and x – axis; also find the area of the shaded region.

2x + 3y = —5


3x — 2y = 12

The given equation is


2x + 3y = – 5


and 3x – 2y = 12


Now, let us find atleast two solutions of each of the above equations, as shown in the following tables.
