If (x- 3)= x , then x=

Options

  1. A1 2 3
  2. B1 2 6
  3. C1 2 5
  4. D3

Correct answer

B. 1 2 6

Step-by-step solution

(x- 3)= x aligned & e^ x- 3 +e^ -(x- 3) 2 = e^x-e^ -x 2 & [ array l x= e^x+e^ -x 2 and x= e^x-e^ -x 2 array ] aligned array lc & e^x e^ - 3 +e^ -x e^ 3 =e^x-e^ -x & e^x 1 3 +e^ -x 3=e^x-e^ -x & 4 e^ -x =e^x ( 2 3 ) e^ 2 x =6 & 2 x= 6 & x= 1 2 6 array
