Part 1: Explain, in complete sentences, which method you would use to solve the following system of equations. (1 point)
Part 2: Explain why you chose that method (1 point)
Part 3: Provide the solution to the system. (2 points)
x – 3y + 2z = –12
x + 2y + 3z = 6
2x – 3y – z = –2

Best ResponseYou've already chosen the best response.0such question is a system of linear equation for further mathematics....so we can reduce it to triangular system and use back substitution...........gaussian elimination would also be appropriate.....or use matrix format with row reduction appplication...actually i am doing an assignment on it

Best ResponseYou've already chosen the best response.0the y is because we have 3 equations with 3 unknowns in it.so the given methods will be right

Best ResponseYou've already chosen the best response.6Yeah I would say substitution too. Solving the first equation for x in terms of y and z yields, x=3y2z12. Substituting the value of x in the second and third equations yields a system of two equations in two unknowns: (3y2z12)+2y+3z=6 2(3y2z12)3yz=2 => 3y2z12+2y+3z=6 6y4z243yz=2 => 5y+z=18 3y5z=22 for z gives, z=5y+18 substituting the value of z in the second equation gives: 3y5(5y+18)=22 3y+25y90=22 28y=112 y=4 substituting the value of y in the first equation: 5(4)+z=18 20+z=18 z=2 substituting the value of y and z in the value of x that we first got ^^ : x=3y2z12 x=3(4)2(2)12 x=12+412 x=4 The solution set is: { (4,2,4) }
