[0010001111]... Hello User... [1001010101]
Here's your answer...
2x+3y = 14
2x-3y = 2
Adding the two equations...
2x+3y+2x-3y = 14+2
4x = 16
x = 4
Substituting x's value in the given equation...
2×4 + 3y = 14
3y = 14-8 = 6
y = 2
x = 4, y = 2

2x-3y=02 -(2)
subtract 2 frm 1...we get

therefore,y=2
put value of y in 1 ....we get x=4
therefore the value of xy=2*4=8
