Question

if x+y=3 then find the values of x and y in x/x+y + x+y/y = 1×1/2

Answer 1

X/x+y+x+y/y=1×1/2
1+y+x+1=1/2
2+y+x=1/2
y+x=1/2-2
y+x=-3/2
y=-3/2-x
Therefore ,
x+y=3
x=3-y
x=3-(-3/2-x)
x=3+3/2+3x
x=9/2+3x
x-3x=9/2
-2x=9/2
x=9/2whole/-2
x=9/2whole/1/2
x=9/2×2/1
x=9
Put x in eq y
y=-3/2-9
y=-3-18whole/2
y=-21/2
Therefore , x=9 , y=-21/2
