Q. if `xy/(x+y)=a`, `xz/(x+z)=b` and `yz/(y+z)=c` ,where a,b and c are other than zero then x equals

If (xy)/(x+y)=a , (xz)/(x+z)=b and (yz)/(y+z)=c , where a , b and c are other than zero, then x equal a.    (abc)/(ab+bc+ca) b.    (2abc)/(ab+bc+ca) c.    (2abc)/(ab+ac-bc) d.    (2abc)/(ac+bc-ab)

If (xy)/(x+y)=a,(xz)/(x+z)=b and (yz)/(y+z)=c where a,b,c are other than zero,find the value of x

Given a=x/(y-z),b=y/(z-x), and c=z/(x-y), where x,y,z and are not all zero,then the value of ab+bc+ca is 0 b.1 c.-1 none of these

Given the system of equation a(x+y+z)=x, b(x+y+z)=y, c(x+y+z)= z where a,b,c are non-zero real numbers.If the real numbers are such that xyz!=0 ,then (a+b+c) is equal to

If (xy)^(a)=z,(yz)^(a)=x and (xz)^(a)=y then what is the value of a ?

If a + x = b + y = c + z + 1 , where a, b,c,x,y,z are non polar distinct real numbers , then |(x, a+y,x + a),(y , b+y , y + b),(z,c+y, z+c)| is equal to :
