Step-by-step explanation:
answer is 1/12
Multiply the first equation by 3 and the second equation by 2:
Subtract the two equation to get rid of the x variable:
Use the value of y to determine the value of x: for example, using the first equation we have
The answer would be your last option, D, 168 cm sq

Answer:
- determinant: -15
- x = 3; y = 4; z = 1
Step-by-step explanation:
The matrix of coefficients has one row corresponding to each equation. The constants in that row are the coefficients of the variables in the equation. Coefficients are listed in the same order on each row. A missing term is represented by a coefficient of 0.
<h3>coefficient matrix, determinant</h3>
The first attachment shows the coefficient matrix and its determinant.
__
<h3>solution</h3>
The solution to the system of equations can be found by left-multiplying the constant vector by the inverse of the coefficient matrix.
This multiplication is shown in the second attachment. It tells us ...
