` y = 5 + ( x ^(2))/(10), x = 2 ` से x = 10 तक

3x - y= 5, 6x - 2y = 10 .

If y = tan ^ (- 1) ((1) / (1 + x + x ^ (2))) + tan ^ (- 1) ((1) / (x ^ (2) + 3x + 3)) + tan ^ (- 1) ((1) / (x ^ (2) + 5x + 7)) then y '(0) = (i) - (3) / (10) (ii) - (5) / (10) (iii) - (7) / (10) (iv) - (9) / (10)

(x + y) ^ (10) = x ^ (8) y ^ (2)

If (10 x + 3y) : (5x + 2y) = 9 : 5 , then show that (2x + y) : (x + 2y) = 11 : 13 .

3x+y=10,x-y=2

{:(3x - y = 5),(6x - 2y = 10):}

If y = [ x + 5 + sqrt(x^2 + 10x + 1)]^n then prove that (x^2 + 10x + 1) y_2 + (x + 5) y_1 - n^2y = 0 .

If 2x + 3y = 10 and 3x + 2y = 5 , then value of x +y is ____
