If 3 ( x - 3 ) = 5 ( 2x + 1 ) , then find the value of x

If 3x - (1)/(2x) = 3 , then find the value of (36x^(4) + 1)/(4x^(2)) .

If x=-3 find the value of 4x^2-5x+3

Given that (5x - 3)^3 + (2x + 5)^3 + 27(4- 3x)^3 = 9(3 - 5x)(2x + 5)(3x - 4) , then the value of (2x + 1) is:

If (x +1/x) = 2 , then find the value of (x^3 + 1//x^3) + (x^(18) + 1//x^(18))

If x -1/x = 5 , then find the value of ( x^2 + 1/x^2 )^( 1/3 )

Let the equation x^(5) + x^(3) + x^(2) + 2 = 0 has roots x_(1), x_(2), x_(3), x_(4) and x_(5), then find the value of (x_(2)^(2) - 1)(x_(3)^(2) - 1)(x_(4)^(2) - 1)(x_(5)^(2) - 1).

If (5x)/3 - 7/2 ((2x)/5 - 1/3) = 1/3 , then the value of x is ________
