Question

. Solve: 6x
+ 3y = 7xy and 3x + 9y = 11xy.​

Answer 1

Answer: (1,3/2)

Step-by-step explanation:

Given equation are 6x + 3y = 7xy

⇒ (6/y) + (3/x) = 7 (i)

And 3x + 9y = 11xy

⇒ (3/y) + (9/x) = 11 (ii)

On multiplying Equation (ii) by 2 and subtracting from Equation(i),

we get

(6/y) + (3/x) = 7

(6/y) + (18/x) = 22

-15/x = - 15

∴ x = 1

On putting this value in Equation (i),

we get

(6/y) + 3 = 7

∴ 6/y = 4

∴ y = 6/4 = 3/2
