Question

Please fast 10 th sum

Answer 1

1) x - y = 8
let,x=2
》2+y=8
》y=8-2
》y=6
(x,y)=(2,6).......(1)

let,x=4
》4+y=8
》y=8-4
》y=4
(x,y)=(4,4)....(2)

let,x= 1
》1+y=8
》y=8-1
》y=7
(x,y)= (1,7)


2)3x-3y=16
let,x=2
》3×2-3y=16
》-3y=16-6
》y=10/-3
y=-3.3
(x,y)=(2,-3.3)

let,x=3
》3×3-3y= 16
》-3y=16-9
》y= 7/-3
》y=-2.3
( x,y)=(3,-2.3)

let,x=1
》3×1-3y=16
》-3y=16-3
》y=13/-3
》y=-4.3
( x,y)=(1,-4.3)
