Sir please give me a detailed solution of this question as it was already asked in previous year paper of 2014 in which we have given that x+2y+2=0, 3x+2y-2=0 and we need to solve these equations graphically
RS Aggarwal, Class 10, chapter 3A, question no 10.
x+2y+2=0….(1)
3x+2y−2=0……(2)
Isolate x from equation (1) and find the value of x and y.
x+2y+2=0
or x=−2y−2
Similarly, isolate x from equation (2) and find the values of x and y.
3x+2y−2=0
or x=(2−2y)/3
Graph:
As expressed in above graph where red line=> x+2y+2=0 & blue line =>3x+2y−2=0
Both the lines intersect each other at point (2,−2).
So, x=2,y=−2
