I need help on these 2 question help me on that please!

2. A system of equations is said to be inconsistent if the system has no solution. Show by using the pivot operation that the following system is inconsistent. $1 + $2 3333 = 7 2$1 + {2 + 51103 = 2 3322 333 = 15 3. (a) Put the constraint set from the standard form of the blending problem into canon ical form with basic variables $1,332,335. The associated basic feasible solution is (6, 21,0, 0, 72). That is, make 501,332, :05 the basic variables so that those columns have a 1 in the appropriate spot and zeros elsewhere. minimize 10321 + 4322 subject to 3531 + 2332 333 = 60 71131 + 2.722 374 = 84 3531 + 6mg 335 = 72 333' 2 0 (b) The objective function for this problem is 10x1 + 4:172. Eliminate $1 and $2 from the objective function by using the results you found from the canonical form in part (a). Now the objective function can be expressed in terms of only $3 and 3:4. Verify that the form reduces to 144 + :23 + 334. (c) Since we are considering only feasible solutions of the constraint set, using part (b), what is the minimal value of the objective function
