ii) Use the matrix approach to solve the following system of equations x+y+z+w=2 x+2y+z+ 2w: = 2 x+2y+3w=-1 x + 3y + 2z+ 4w = 1. Write your solution as the vector x У Z W Note: remember to write a vector like = 2 0- 2 -1 1 as <2,2,-1,1>. ii) Use the matrix approach to solve the following system of equations x+y+z+w=2 x+2y+z+ 2w: = 2 x+2y+3w=-1 x + 3y + 2z+ 4w = 1.
