`4x + (6)/(y) = 15` and `6x -(8)/(y) = 14`, and hence, find p if y = px - 2.

Solve: 4x+(6)/(y)=156x-(8)/(y)=14 and hence find p if y=px-2

If 2x +3y = 30 and (x+y)/y = 11/8 , then find the value of 5y + 6x

Solve: (2)/(x)+(2)/(3y)=(1)/(6) and hence find 'a' for which y=ax-4

If (15x + 16y)/(25x + 4y) = (7)/(6) , then find x:y.

If r_(1), r_(2) " and " r_(3) are the radii of the circle x^(2) + y^(2) - 4x + 6y = 5 , x^(2) + y^(2) + 6x - 4y = 3 " and " x^(2) + y^(2) - 2x + 4y = 8

Let A be the point of intersection of the lines 3x 2y = 14 , 5x – y = 6 and B be the point of intersection of the lines 4x 3y = 8 , 6x y = 5 . The distance of the point P(5, –2) from the line AB is

Find the angle between the planes : (i) 3 x - 6y - 2z = 7 " " 2x + y - 2z = 5 (ii) 4 x + 8y + z = 8 " " and y + z = 4 (iii) 2 x - y + z =6 " " and x + y + 2z = 7 .

If x/6+y/15=4 and x/3-y/12=4 3/4 find x and y.
