Answer 2

Answer:

$xy \: = \: 8$

Step-by-step explanation:

$2x + 3y = 14 \: \: .....(1) \\ \\ 2x - 3y = 2 \: \: .....(2) \\ \\ adding \: both \: the \: equations \: . \\ we \: get \: \\ \\ 4x = 16 \\ \\ x = \frac{16}{4} \\ \\ x = 4 \\ \\ substituting \: the \: value \: of \: x \: \\ \\ in \: the \: equation \: (1). \\ we \: get \: \\ \\ 2(4) + 3y = 14 \\ \\ 8 + 3y = 14 \\ \\ 3y = 14 - 8 \\ \\ y = \frac{6}{3} \\ \\ y = 2 \\ \\ now \: the \: value \: of \: xy \: \\ \\ xy \: = \: 4 \times 2 \\ \\ xy \: = \: 8$
