Answer 1

Answer:

9( y-1) -8( x+1)=1

9 y - 9 -8 x -8=1

9 y -8 x -17= 1

9 y - 8 x =1+17

9 y -8 x =18. EQ 1

3( y-1) +4(x+1) =2

3 y -3 +4 x +4= 2

3 y +4 x +1=2

3 y +4 x =1. EQ 2

EQ 2 me 3 se guna karakar EQ 1 jodne par

9 y -8 x =18

(3 y +4 x =1)×3

9 y-8 x = 18

9 y +12 x =3

+. +. +

------------------

4 x= 21

x= 21/4

x ka man EQ 1 me rakane par

9 y -8 x =12

9 y-8 ×(21/4) =12

36 y -168=48

36 y= 48+168

36 y =216

y=6
