Question

**Hello friends**
10 points....
Please try to Solve..

(a) 3/x+3-2/y-3=-1/2 and 9/x+3+1/y-3=2

(b) 6x+3y=6xy and 2x+4y=5xy

Answer 1

b) 6x + 3y = 6xy ----- ( 1 )
2x + 4y = 5xy ----- ( 2 )

solve equations by elimination method , As :
Now multiply by 3 in equation 2 , and get
6x + 12y = 15xy ----- ( 3 )

subtract equation 1 from equation 3 and get
9y = 9xy
x = 1

multiply 4 in equation 1 and by 3 in equation 2 , and get
24x + 12y = 24xy ----- ( 4 )
6x + 12y = 15xy ----- ( 5 )
Now,subtract equation 5 from equation 4 and get
18x = 9xy
y = 2

Hence, x = 1 and y = 2

i can only solve b) part...

hope this will help you
