An important question from RS Aggarwal, Chapter- Linear Equations in two variables in which we have given the equations 2x+3y+5=0, 3x-2y-12=0 and we need to solve the given equations graphically

2x+3y+5=0….(1)
3x−2y−12=0……(2)
Isolate x from equation (1) and find the value of x and y.
2x+3y+5=0
2x=−3y−5
x=(−3y−5)/2
Similarly, isolate x from equation (2) and find the values of x and y.
3x−2y−12=0
or 3x=2y+12
or x=(2y+12)/3
Graph:
Both the lines intersect each other at point (2,−3).
So, x=2,y=−3
