Given the following system of linear equations $($use your knowledge of the inverse of matrices from ENGR$11)$:

$x+2y+3z=1$

$4x+5y+6z=1$

$7x+8y=1$

Hint: Define a matrix A that corresponds to the coefficients. Define a matrix $B$ that corresponds to the constants. Use $Ax=B$ and solve for $x.$ Display the result as $"x=$dots,$y=$ and $z=,\text{'}$ in one line of code using the disp command.
