Solve the system by using a matrix equation
3x-5y=3
3x-4y=3

B. (1,0)

Step-by-step explanation:

1. We will use the matrix method to solve this problem.

3-53

3-43

2. Apply to Row2 : Row2 - Row1.

3-53

010

3. Simplify rows.

3-53

010

Note: The matrix is now in row echelon form.

The steps below are for back substitution.

4. Apply to Row1 : Row1 + 5 Row2.

303

010

5. Simplify rows.

101

010

Note: The matrix is now in reduced row echelon form.

6. Therefore,

x=1

y=0

or (1,0).

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

$3,200 x 7.25% = $3,200 x .0725 = $232 interest monthly

$232 monthly x 12 annual = $2, 784
