Answer: X = y - yi - 7i

               Y = (x + 7i)/(1 - i)

Step-by-step explanation: for the case of (X) you only need to pass the 7i to the other side with the subtraction sign (-7i), then we get this equation:

x + 7i = y − yi

X = y - yi - 7i

in the case of the (Y), first we select the common multiple.

y - yi = y(1 - i)

if we replace it in the original expression, we get the following equation:

x + 7i = y(1 - i)

after that you can pass the value (1 - i) to the other side dividing,

Y = (x + 7i)/(1 - i)

a_{1,3} = 9

Step-by-step explanation:

The elements of matrices are represented in the form

a_{r,c}

Here r is the row number and c is the column number.

Given matrix is:

A = \left[\begin{array}{ccc}3&6&9\\2&4&8\end{array}\right]

The elements of matrix will be represented by a_{r,c}

We have to find a_{1,3}

Which means that the first row and third column.

The first row is: 3   6    9 and the element in third column is: 9

So,

a_{1,3} = 9
