One of the most important and conceptual question from linear equations in two variables in which we have given the equations 2x-3y+13=0, 3x-2y+12=0 and we have to solve these equations graphically

2x−3y+13=0….(1)
3x−2y+12=0……(2)
Isolate x from equation (1) and find the value of x and y.
2x−3y+13=0
or 2x=3y−13
or x=(3y−13)/2
Similarly, isolate x from equation (2) and find the values of x and y.
3x−2y+12=0
or x=(2y−12)/3
Graph:
Both the lines intersect each other at point (−2,3).
So, x=−2,y=3
