Question

solve for X 1 / A + B + X is equals to 1 / a + 1 / B + 1 / x​

Answer 1

x=-a or x=-b

Step-by-step explanation:

1/a+b+x-1/x=1/a+1/b

x-(a+b+x)/x(a+b +x)=a+b/ ab

-(a+b)/x(a+b+x)=a+b/ab

x(a+b+x)=-ab

ax+bx+x²=-ab

x²+ax+bx+ab=0

x(x+a)+b(x+a)=0

(x+a) (x+b)=0  

x+a=0 or x+b=0

x=-a or x=-b
