If ` 29 x + 37y = 103 and 37x + 29y = 95 ` then

21 + 3.7 xx 2.9 = ?

If the circles x^(2) + y^(2) - 2lambda x - 2y - 7 = 0 and 3(x^(2) + y^(2)) - 8x + 29y = 0 are orthogonal then lambda =

Solve :62x+37y=13 and 37x+62y=-112

23 x - 29 y = 98 , 29 x - 23 y = 110

Solve For x and y : 71 x + 37 y = 253 , 37 x + 71 y = 287 .

If 9x^2+y^2=37 and xy = 2 , x, y> 0 , then the value of (27x^3+y^3) is : यदि 9x^2+y^2=37 और xy = 2 , x, y> 0 , तो (27x^3+y^3) का मान ज्ञात कीजिए ।

If x^(2) + y^(2) =37 and xy = 6 : find x-y

If x^(2) + y^(2) = 37 and xy = 6, find x+y

Solve for x and y , 37x + 43 y = 123, 43 x + 37 y = 117
