Question 1117716
<font face="Times New Roman" size="+2">


1.  Solve the last equation for *[tex \Large w].


2.  Substitute the value of *[tex \Large w] you discovered in step 1 into the third equation and then solve for *[tex \Large z].


3.  Substitute the value of *[tex \Large w] from step 1 and the value of *[tex \Large z] from step 2 into the second equation and then solve for *[tex \Large y].


4.  Substitute the values of *[tex \Large w], *[tex \Large \ z], and *[tex \Large y] from the first three steps into the first equation and solve for *[tex \Large x]

The way you are asking for the answer is incorrect.  A list of the values of the four variables is NOT the solution set of the 4X4 system of equations.  The solution set of this system has a single element, namely the ordered quadruple of the form *[tex \Large (x, y, z, w)].  The solution set would then need to be written:  *[tex \Large \{(x, y, z, w)\}].
