Here's how you solve this problem:

1) Multiply the first equation by 2 (result:2x+2y=8).

2) Add both equations together (result:2x+x+2y-2y=8-5)

3) Simplify (result:3x=3)

The answer is 3x=3.

This could be simplified more, however, to equal x=1, since both sides are divisible by 3.

p.s. Have a good day!

These are matrices one dimensional with one column and 3 rows each.

-The product of the matrices is obtained by multiplying the correspond values and summing up;

$pq=\left[\begin{array}{ccc}3\\2\\-1\end{array}\right] \times\left[\begin{array}{ccc}5\\-1\\2\end{array}\right] \\\\\\\\=(3\times 5)+(2\times -1)+(-1\times 2)\\\\=15+-2+-2\\\\=11$

Hence, the product of p and q is 11
