Great!!!

Two of three variables should be same, and all variables are not zero.

Not the same, the sign is flipped.

Easy question

@pe3akpe3et99 5 күн бұрын

if u multiply everything by (m+n+x)*x, you get that it becomes a quadratic equation in x, so it's obv there are only 2 solutions x= -m and x=-n

This is not simplification, it's conviluting what was already simplified.

is m+n≠0 a necessary condition?

@SarathBapu 2 күн бұрын

If m+n=0 => 1/m + 1/n = 0 always. In such situation, the solution would be m,n,x € Z, m,n,x!= 0 and m+n != 0

m+n+x=0?

@honestadministrator 4 күн бұрын

(m + n) (1/(m n) + 1/(x (m + n + x))) = 0 (x + m) (x + n) /( m n x ( m + n + x)) = 0 Hereby x = - m, - n

@user-xk8ux6qc2j 5 күн бұрын

Easier solution: 1/m + 1/n = 1/(m+n+x) - 1/x (m+n)/mn = -(m+n)/x(m+n+x) 1/mn = -1/x(m+n+x) x(m+n+x) = -(mn) There you have 4 cases. (1) x = -m => m + n + (-m) = n which is true. (2) x = m => m + n + (m) = -n => x = m = -n . (3) x = -n => m + n + (-n) = m which is true. (4) x = n => m + n + (n) = -m => x = n = -m Solutions: x = -m or x = -n.

line 2 ->line3 , if m=-n you cannot divide by 0

@@blancheteigne9865 True, that makes it actually more simple, since we would only have cases (1) and (3), thanks for spotting the mistake!!

You have multiple errors where you are missing grouping symbols: (m + n)/(mn) = -(m + n)/[x(m + n + x)], etc.
