The Sign Trap

CBSE Class 10 · Solve it one decision at a time. A wrong pick earns a nudge, never the answer.

Step 1 of 8

The problem

Solve for xx: 1a+b+x=1a+1b+1x\dfrac{1}{a + b + x} = \dfrac{1}{a} + \dfrac{1}{b} + \dfrac{1}{x}, where aa and bb are non-zero and a+b≠0a + b \neq 0.

Step 1 · Your move

Before the guided steps, which values of xx did you get?

x≠0,a+b+x≠0x \neq 0,\quad a + b + x \neq 0
