18 = 10 + 2k
move 10 to the other side
sign changes from +10 to -10
18-10=10-10+2k
18-10= 2k
8= 2k
divide by 2 to get k by itself
8/2= 2k/2
Cross out 2 and 2 , divide by 2 and then becomes 1*1*k= k
k=8/2
Answer: k= 4
Answer: Choice B

Explanation:
The given matrix is
![\left[\begin{array}{cc|c}1&5&11\\4&-6&-3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D1%265%2611%5C%5C4%26-6%26-3%5Cend%7Barray%7D%5Cright%5D)
The numbers to the right of the vertical bar represent the values on the right hand side of each equation in the final answer.
The numbers to the left of the bar represent the x and y coefficients of the equations. The first number of any given row is the x coefficient. The second number is the y coefficient.
For instance, the first row has 
to indicate the x coefficient is 1, and the y coefficient is 5. We end up with 1x+5y or simply x+5y. Putting everything together, the first equation would be x+5y = 11
Through similar steps, the second equation is 4x-6y = -3
The maximum mortgage payment allowed for someone with an annual salary of $83,750 would be $2512.50 per month.
<h2><u>What is the standard 28/36 guidelines?</u></h2>
To determine, using the standard 28/36 guidelines, what is the maximum mortgage payment allowed for someone with an annual salary of $83,750, the following calculation must be made:
- Annual salary x 36% / months = X
- ((83750 x 36) / 100) / 12 = X
- (3,015,000 / 100) / 12 = X
- 30150 / 12 = X
- 2512.50 = X
Therefore, the maximum mortgage payment allowed for someone with an annual salary of $83,750 would be $2512.50 per month.
