+ 3 ![\left[\begin{array}{ccc}1&-1\\-6&3\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%26-1%5C%5C-6%263%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Multiply each element in the matrices by the scalar quantity, that is
= ![\left[\begin{array}{ccc}8&-10\\-4&2\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D8%26-10%5C%5C-4%262%5C%5C%5Cend%7Barray%7D%5Cright%5D)
+ ![\left[\begin{array}{ccc}3&-3\\-18&9\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%26-3%5C%5C-18%269%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Add corresponding elements from each matrix
= ![\left[\begin{array}{ccc}8+3&-10-3\\-4-18&2+9\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D8%2B3%26-10-3%5C%5C-4-18%262%2B9%5C%5C%5Cend%7Barray%7D%5Cright%5D)
= ![\left[\begin{array}{ccc}11&-13\\-22&11\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D11%26-13%5C%5C-22%2611%5C%5C%5Cend%7Barray%7D%5Cright%5D)

Answer:
7y + 3 = 3x + 11
7y = 3x + 11 - 3
7y = 3x + 8
y = 3x + 8 / 7
7y + 3 = 3x + 11
7y + 3 - 11 = 3x
7y - 8 = 3x
x = 7y - 8 / 3
