$x_c=1-0\mathrm{.}70-x_B$

a$)$ Rearrange the system of equations into the form needed for MATLAB so that the coefficients for

the A matrix and variables are on the left$-$hand side and the constants for the $b$ vector are on the

right$-$hand side of the system of equations.

b$)$ Then use the MATLAB template file provided in class $($lecture notes, course website, and in

Section $1\mathrm{.}10)$ to solve for $x$ and the values for the unknowns. Include in the homework

submission the values of the unknowns that you interpret from the $x$ solution, INCLUDING ALL

APPROPRIATE UNITS. Provide a copy of the relevant section of the MATLAB code, which

could take any of the following forms

code segment and answers directly copied and pasted into a document

a snip or screenshot $($DO NOT TAKE A PICTURE OF YOUR COMPUTER WITH YOUR

PHONE$)$
