The system of equations can be written in augmented matrix form as ...
![\displaystyle\left[\begin{array}{cc|c}-\frac{1}{2}&3&-4\\-1&-1&-1\end{array}\right]](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D-%5Cfrac%7B1%7D%7B2%7D%263%26-4%5C%5C-1%26-1%26-1%5Cend%7Barray%7D%5Cright%5D)
The value of x found by Cramer's rule is the ratio of two determinants. The numerator is the coefficient matrix with the x-column replaced by the constant column. The denominator is the coefficient matrix.
Step-by-step explanation:
To find - Enter five expressions: a sum, a difference, a product, a quotient, and one that involves at least two operations that have the value of -3/4 (the fraction)
Solution -
Expression for sum is -
1/4 + (-1) = -3/4
Expression for difference is -
(1/4 - 1) = -3/4
Expression for product is -
(-3/2)(1/2) = -3/4
Expression for quotient is -
(1 - 4)/4 = -3/4
Expression that involves at least two operations is -
-(1/4 + 2/4) = -3/4
