Problem $5$: The Big M Method and The Two$-$Phase Method Consider the following problem. minimize Z $=3$x$1+2$x$2+4$x$3$ subject to $2$x$1+$ x$2+3$x$3=603$x$1+3$x$2+5$x$3120$ x$1,$ x$2,$ x$30.1.$ Using the Big M method, work through the simplex method step by step to solve the problem. Identify the optimal solution obtained. $2.$ Using the two$-$phase method, work through the simplex method step by step to solve the problem. Identify the optimal solution obtained.
