If `(1)/(8!)+(3)/(7!)=(x)/(9!)` then x is:

If sqrt(1+(7)/(9))=1+(x)/(3) , then x =

if (x-1)/(x+1)=7/9,then x=?

Let (x-1) is a factor of x^(4)-7ax^(2)+3bx+9 and (x-2) is a factor of (x^(3))/(8)+(3bx^(2))/(4)+ax+1 ,then (27)/(2)|a+b| is

Solve : (7x +3)/(4) + (9x -5)/(8) = (16x-3)/(16) The following steps are involved in solving the above problem. Arrange them in sequential order (A) x = (-5)/(30) = (-1)/(6) (B) (7x + 3)/(4) + (9x -5)/(8) = (16x-3)/(16) rArr (14x + 6 + 9x -5)/(8) = (16x -3)/(16) (C) (23x + 1)/(8) = (16x -3)/(16) rArr 23x + 1 = (16x -3)/(2) (D) 46x + 2 = 16x - 3 rArr 30 x = -5

If (x,3)+(2,5)=(7,8) then x is equal to a)2 b)5 c)7 d)9

(3x+1)/(6)+(2x-3)/(7)=(x+3)/(8)+(3x-1)/(14)
