Write the augmented matrix for the system of linear equations.
7x + 4y = 53
5x − 9y = −57
I got the answer below but my online assignment said it's wrong please help me
1 0 3
0 1 8
I know this is a repost
That is the SOLUTION
I gave you the augmented matrix, no work required for that
7 4 53
5 -9 -57
The solution is x = 3 and y = 8
To write the augmented matrix for the given system of linear equations, we need to arrange the coefficients of the variables and the constants in a matrix form.
Let's start with the equations:
1) 7x + 4y = 53
2) 5x - 9y = -57
To form the augmented matrix, we arrange the coefficients of x and y from each equation in a row, and the constant terms on the right-hand side of the matrix. The matrix will have three columns: one for the x coefficients, one for the y coefficients, and one for the constants.
The augmented matrix for this system of linear equations will look like this:
[ 7 4 | 53 ]
[ 5 -9 | -57 ]
Make sure you check your work and confirm that all the numbers are accurately transcribed into the matrix.
