let us solve the following linear equation in two variables by elimination method and check them graphically :
8x + 5y - 11 = 0
3x - 4y - 10 = 0
❤only for maths experts❤
✔ I need best nd right answers ✔
Inflameroftheancient:
y = - 1, x = 2, graphically they intersect at a common point of (2, -1)

hiiii mate
8x+5y-11=0. -----(i) ×3
3x-4y-10=0 -----(ii) ×8
24x+15y-33=0-----(iii)
24x-32y-80=0-----(iv)
by using elimination method
24x+15y-33=0
24x-32y-80=0
- + +
47y+ 47=0
y=-47/47=-1
put y=-1 in equation (I)
8x+5(-1)=11
8x-5=11
8x=11+5
8x=16
x= 16/8
X=2
