can someone show me how to solve this:

directions: pivot once as indicated in each simplex tableau. Read the solution from the result. the number that is highlighted is row 2 column 3 which is the 5

the matrix is a 4 X 8

under column one it reads as:

x1/x2/x3/s1/s2/s3/z
4/2/3/1/0/0/0=22
2/2/5/0/1/0/0=28
1/3/2//0/1/0=45
-3/-2/-4/0/0/0/1=0
