`tan^(-1)(x+7)+tan^(-1)(5/(3-x))=(pi)/(4)`

Q.solve for x ,tan ^(-1)(2x)+tan^(-1)(3x)=(pi)/(4)

tan^(-1)(x/2)+tan^(-1)(x/3)=(pi)/(4)

If tan^(-1)(2x)+tan^(-1)(3x)=(pi)/(4) , then find the value of x.

tan^(-1)(x-1)+tan^(-1)(x+1)=(pi)/(4)

Prove that : tan^(-1)(1)/(5)+tan^(-1)(1)/(7)+tan^(-1)(1)/(3)+tan^(-1)(1)/(8)=(pi)/(4)

Prove that: tan^(-1)(1)/(7)+tan^(-1)(1)/(13)=tan^(-1)(2)/(9)tan^(-1)+tan^(-1)(1)/(5)+tan^(-1)(1)/(8)=(pi)/(4)tan^(-1)(3)/(4)+tan^(-1)(3)/(5)-tan^(-1)(8)/(19)=(pi)/(4)tan^(-1)(1)/(5)+tan^(-1)(1)/(7)+tan^(-1)(1)/(3)+tan^(-1)(1)/(8)=(pi)/(4)cot^(-1)7+cot^(-1)8+cot^(-1)18=cot^(-1)(1)/(13)

Solve the following equation for x:tan^(-1)((1)/(4))+2tan^(-1)((1)/(5))+tan^(-1)((1)/(6))+tan^(-1)((1)/(x))=(pi)/(4)

tan^(-1)5-tan^(-1)3+tan^(-1) ((7)/(9))=(pi)/(4)

Prove that: tan^(-1)((1)/(5))+tan^(-1)((1)/(7))+tan^(-1)((1)/(3))+tan^(-1)((1)/(8))=(pi)/(4)

IF tan ^(-1) 2x + tan ^(-1) 3x =(pi)/(4) , then x=
