x+5=12 x=?

3 x + 5y = 12, 5x + 3y = 4 .

If x= 11, then the value of x^5 -12x^4 +12x^3 -12x^2+12x-1 is - यदि x= 11 हो तो x^5 -12x^4 +12x^3 -12x^2+12x-1 का मान क्या होगा?

If the mean of 2x, 5, 3x, 12, 5x, 17 and6 is 20, then x = ..........

Factorise : 3 - 5x + 5y - 12(x-y)^(2)

{:(3x + 5y = 12),(3x - 5y = - 18):}

Find the value of x=> 5:x=3:12 .

If Cot x = (5)/(12) then sec x + cosec x = ?

Find the roots of 3x^(2) - 5x - 12 = 0 .

Find the roots of 3x^(2) - 5x - 12 = 0 .

Solve the following: (x^2 -5x+12)/(5x-12) = (x^2 -x-4)/(x+4)
