If you cannot see the table, hold CTRL and press the $+_cfw_=$ button at the top of the keyboard.
Since it is a geometric sequence, you know that "R" is a multiplier rate. Therefore, by using your
two given values of 16/3 and 6
1. Factor the quadratic expression on the denominator.
2. Split the fraction accordingly
3. Multiply both sides of the equation by (x + 4)(x + 2)
4. Distribute
5. Factor the new expression so that the form on the right looks similar to the left side
6. Th
(2 by 3) times (3 by 2) makes a (2 by 2) matrix.
To find row1 column1 of the (2 by 2) matrix,
multiply row1 of matrix A by column 1 of matrix B and add each individual product together.
To find row1 column2 of the (2 by 2) matrix,
multiply row1 of matrix

1st Row = 3, 5
2nd Row = 2, 3

Matrix A:
1st Row: 1, 5
2nd Row: 3, 5
Matrix B:
1st Row: X
2nd Row: Y
Matrix C:
1st Row: 1
2nd Row: 5
Matrix A times Matrix B = Matrix C
So, Matrix B = (inverse of Matrix A) times Matrix C
Inverse of Matrix A
