An important and exam oriented question from linear equations in two variables as it was already asked in previous year paper of 2005 in which we have given that 2x-5y+4=0, 2x+y-8=0 and we have been asked to solve these equations graphically
RS Aggarwal, Class 10, chapter 3A, question no 4
2x−5y+4=0….(1)
2x+y−8=0……(2)
Isolate x from equation (1) and find the value of x and y.
2x−5y+4=0
or 2x=5y−4
x=(5y−4)/2
Similarly, isolate x from equation (2) and find the values of x and y.
2x+y−8=0
or y=8−2x
Graph:
Both the lines intersect each other at point (3,2).
So, x=3,y=2
