Question

2x-3/y=9;3x+7/y=2 please solve this question

Answer 1

Answer:

x=49/16

y= -24/23

Step-by-step explanation:

let 1/y=a

2x-3a=9 –1

3x+7a=2 –2

mudltiplying eq.1 by 3 and eq.2 by 2

6x-9a=27 –3

6x+15a=4 –4

eq.3 - eq.4

-24a=23

a= -23/24

1/y= -23/24

y= -24/23

y= -1-1/23

inserting value of y in eq.1

2x-(3×-23)/24=9

2x+69/24=9

2x=9-69/24

2x=(216-69)/24

x=147/(24×2)

x=147/48

x=49/16
