Question

1IF 2x+3y=14 and 2x-3y = 2, find the value of xy.
Fint Use (2x + 3y)2 – (25 - 3y)2 = 24xy]​

Answer 1

Answer:

8

Step-by-step explanation:

2x + 3y = 14

2x - 3y = 2

Add both the equations

4x = 16

x = 4

Sub in 1st equation

2(4) + 3y = 14

8 + 3y = 14

3y = 6

y = 2

Therefore xy = 4(2) = 8
