4/(x+1)+ 7/(4(2-y))=9
3/(2(x+1))+7/(2-y)=7
Thanks.
3/(2(x+1))+7/(2-y)=7
Thanks.

put 1/(x+1) = a and 1/(2-y) = b
now your equations become
4a + (7/4)b = 9..............1
(3/2)a + 7b =7................2
multiply equation 1 by 8 and equation 2 by 2
now equation becomes
32a + 14b = 72
3a + 14b = 14
solving these equations a=2 and b= (8/14)
now you have to solve for y
b = 1/(2-y)
8/14 = 1/(2-y)
2-y = 14/8
y = 2-(14/8)
y = 2/8 or 1/4
now your equations become
4a + (7/4)b = 9..............1
(3/2)a + 7b =7................2
multiply equation 1 by 8 and equation 2 by 2
now equation becomes
32a + 14b = 72
3a + 14b = 14
solving these equations a=2 and b= (8/14)
now you have to solve for y
b = 1/(2-y)
8/14 = 1/(2-y)
2-y = 14/8
y = 2-(14/8)
y = 2/8 or 1/4
