Question

solve using cross multiplication 2x+3y-17=0 and 3x-zy-6=0​

Answer 1

Step-by-step explanation:

x - y = -3 …..(1)

2x + 3y = 29 …..(2)

From Eq. (1)

x + 3 = y

or, y = x + 3

On putting the value of y in Eq.(2), we get

2x + 3 ( x + 3 ) = 29

or, 2x + 3x + 9 = 29

or, 5x = 29 - 9

or, 5x = 20

∴ x =

20

= 4

5On putting the value of x in Eq. (1), we get

4 - y = -3

or, 4 + 3 = y

∴ y = 7

Hence, x = 4 and y = 7

Answer 2

Step-by-step explanation:

x = 4 and y = 7
