Which is an augmented matrix for the system of linear equations? negative 4 x plus 3 y is equal to 216 10 x minus 4 y is equal to negative 156

An augmented matrix lists the coefficients of the variables first, followed by the constants on the right side of each equation. The equations give rows (−4, 3, 216) and (10, −4, −156). Choice A has exactly these rows, including the negative signs.
