Somehow, I am confused with the given matrix. Because normally, when the system of equations is given as:ax + by = cdx + ey = fthe array would be written this way:I just assume that the layout of the given corresponds to this system of equations:4x + 8y = 02x + 5 = 6So it is written as In order to resolve this, the array should look like this where x and y are the answersSo, the first thing to do is to apply this pattern: Row 2 = Row 1 - 2*Row 2. The result beNext, Row 1 = (Row 1/4) + R2:finally, Row 2 = Row 2 / -2:therefore, the answer is x=-12 y=6.
