A student is trying to solve the following system byusing elementary row operations:

x3y2z=0

2x7y+4z=0

y8z=0

They performed some elementary row operations and got to a point where they have following matrix

100311288000 Now, they want to get 0 in place of entry a₃₂. (row three, second column)

a) What should be the entries for the new row 3? Only write entries of row 3 without brackets separated by single space.

b)Now, they want to use Gaussian elimination method to solve the system. Given, solution for z =t, tR, solve for x and y.

Write solution only for x and y
