x/2-y/9=6
9x-2y/18=6
9x-2y=108-------1)
x/7+y/3=5
3x+7y/21=5
3x+7y=105-------2)
To perform Elimination method , mutliply eq. 2 with 3
By elimination method..
3(3x+7y)=105×3
.
9x+21y=315
- (9x-2y=108)
----------------------
0+23y=207
y=207/23
a. Y =9ans..
b. X=108+2y/9(by eq.1)
=108+2×9/9
=14 ans...
