1. The problem is to find the system of linear equations corresponding to the given augmented matrix:
$$\begin{bmatrix}4 & 0 & 0 \\ 7 & -4 & 0 \\ 0 & 3 & 3\end{bmatrix}$$
2. The augmented matrix represents the coefficients of variables $x_1$, $x_2$, and the constants on the right side of the equations.
3. From the matrix, the system of equations is:
$$4x_1 + 0x_2 = 0$$
$$7x_1 - 4x_2 = 0$$
$$0x_1 + 3x_2 = 3$$
4. Simplify the equations:
$$4x_1 = 0$$
$$7x_1 - 4x_2 = 0$$
$$3x_2 = 3$$
5. Solve for $x_1$ and $x_2$:
From the first equation:
$$4x_1 = 0 \implies x_1 = \frac{\cancel{4}x_1}{\cancel{4}} = 0$$
From the third equation:
$$3x_2 = 3 \implies x_2 = \frac{\cancel{3}x_2}{\cancel{3}} = 1$$
6. Check the second equation with these values:
$$7(0) - 4(1) = 0 - 4 = -4 \neq 0$$
This indicates the system is inconsistent as given, but the system from the matrix is:
$$4x_1 = 0$$
$$7x_1 - 4x_2 = 0$$
$$3x_2 = 3$$
