If 2x+3x eqal to 14,2x-3y equal to 2,find the value of xy​

Answer»

Answer:

xy = 8

Step-by-step explanation:

2x + 3y = 14 ..............(1)

2x - 3y = 2 .............(2)

ADDING (1) and (2) we get

4x = 16

x = 4.

Now, putting x = 4 in any equation ( (1) or (2) )

We get y = 2.

Now xy = 4 x 2 = 8.
