Solve `(7)/(x) + (8)/(y) = 2` and `(2)/(x) + (12)/(y) = 20`.

Solve : (7)/(x) + (8)/(y) = 2 and (2)/(x) + (13)/(y) = 22

Solve (20)/(x + y) + (3)/(x - y) = 7 and (8)/(x - y)- (15)/(x + y) = 5 .

Solve (20)/(x + y) + (3)/(x - y) = 7 and (8)/(x - y)- (15)/(x + y) = 5 .

Solve the pair of equations : (3)/(x) + (2)/(y) = 7 (5)/(x) - (4)/(y) = 13 Hence find the value of 27x - 12y .

Solve for x and y (2)/(x)+(3)/(y)=2, (8)/(x)-(6)/(y)=2

Solve x-(y)/(5) =6, y-(z)/(7)=8 , z-(x)/(2) = 10

Solve : (3x + 2y) (7x - 8y)

Solve by cross-multiplication method. (i) 8x-3y=12,5x=2y +7 (ii) 6x+ 7y -11 =0, 5x+ 2y =13 (iii) (2)/(x)+(3)/(y) =5, (3)/(x) -(1)/(y) +9=0
