Question

Find two solutions of following equations :

(i) 4x + 3y = 12
(ii) 2x + 5y = 0
(iii) 3y + 4 = 0

{NCERT MATHS CLASS 9th)

Answer 1

HELLO DEAR,

(1)..LET,X=0
WE GET,
3Y=12
Y=4

The solution is(0,4)

and we take,Y=0

WE GET,

4X=12
X=3
ANOTHER SOLUTION IS (3,0)



(2).LET,X=0

WE GET,
5Y=0
Y=0

SOLUTION IS (0,0)

AND

TAKE Y=0

WE GET,

2X=0

X=0

{noth solution is same hence we not get different Solution}


(3).LET X=0

0.X+3Y+4=0

3Y=-4

Y=-4/3
SOLUTION IS (0,-4/3)

and
we take,

Y=1

WE GET,
3Y=-4

Y=-4/3

SOLUTION IS (1,-4/3)

solutions are same

IN fact (K,-4/3)

for all real values of x

I HOPE ITS HELP YOU DEAR,
THANKS
