The system of equations represents the costs of three fruit baskets. a = cost of a pound of apples 2a + 2b +g + 1.05 = 6.00. b = cost of a pound of bananas 3a + 2b + 2g + 1.05 = 8.48. g = cost of a pound of grapes 4a + 3b + 2g + 1.05 = 10.46. Write the augmented matrix. Enter it into your calculator. Find the cost of a pound of each fruit.

The description below describes how to carry out row operations to solve the system of equations above. You can also do these steps on paper without the use of a calculator. To solve the system using row operations, we first need to put the system of equations into an augmented matrix. For the system above, the augmented matrix is.

An augmented matrix is used to show the numeric coefficients and the constants in a system of equations. In such a matrix all the x’s, y’s, z’s etc. must be in the same column and the rows must contain individual equations. A coefficient matrix is the part of the augmented matrix that contains the numeric coefficient of the variables.

An augmented matrix is a matrix which contains the coefficients of the variables, the last column contains the numbers on the right-hand side of the equations. Reduced row echelon form is a matrix in row echelon form with every column that has a leading 1 having 0's in all other positions.

A system of equations that is formed using a singular matrix has either 0 solutions or an infinite number of solutions. The only way to determine which of these is the case is to use the augmented matrix and simplify as long as possible. Ultimately, the augmented matrix will yield a line with the following format: 0 0 0 … 0 : c. where ...

Interpreting the Augmented Matrix. 7. Now that the augmented matrix is in its reduced row-echelon form, what is the solution to this system of equations? Answer: x = 2, y = –1 and z = 3, or the point (2, –1, 3) 8. Verify the solution by substituting your solution into the original system of equations manually or using the calculator ...

Note that if the matrix you are entering is an augmented matrix, the last column of your matrix will represent the constants after the “equals” sign of your system of equations. Insert the entries of the matrix, pressing the [ENTER] key after each entry. When finished entering all entries, press [2nd] [QUIT].
