Long description

The image shows the following.

X equals Numerator determinant upon Denominator determinant

Numerator determinant values are as follows.

  • Row 1: 10, 3, 1

  • Row 2: 8, negative 1, negative 2

  • Row 3: 6, 2, negative 3

A note mentions “Numerator determinant, in which column with Xs is replaced by column of numbers to the right-hand side of the equal sign”

A note against the first column reads “Coeffi¬cients for right-hand side”

Notes against the second and third columns read “Coe¬fficients for Y” and “Coe¬fficients for Z” respectively.

Denominator determinant values are as follows.

  • Row 1: 2, 3, 1

  • Row 2: 4, negative 1, negative 2

  • Row 3: 5, 2, negative 3

A note mentions “Denominator determinant, in which coeffi¬cients of all unknown variables are ...
