I) a=3 and b=-8
2)a=4 and b=-5
2)a=4 and b=-5
haseebfatima123:
explain it briefly
substitute x=a and y=0 in first equation u get a value
substitute x=0 & y=b in first equation u get b value
simillarly substitute in 2nd equation
pls write and show
in order

i)8x-3y=24
(a,0)
8a-3(0)=24
8a=24
a=24/8=3
(0,b)
8(0)-3b=24
-3b=24
b=24/-3=-8
ii)5x-4y-20=0
5x-4y=20
(a,0)
5a-4(0)=20
5a=20
a=20/5=4
(0,b)
5(0)-4b=20
-4b=2
b=20/-4
b=-5
i)a=3 b=-8
ii)a=4 b=-5
hope it helps
