Question 636095
The system of equations


<img src="http://latex.codecogs.com/gif.latex?\begin{array}{rl} 7x+4y+5z &= 62 \\5x+3y+2z &= 47 \\3x+7y+8z &= 63 \\ \end{array}" title="x" />


Translates to the augmented matrix

Note: you're essentially writing the coefficients in the order you see them in the equations to form the matrix.
