I am having trouble finding the matrix X= of this equation I could use some help.

Given the input-output matrix below, find the output matrix if final demand changes to 400 for water, 180 for electric power, and 700 for agriculture. Industry Electric Water Power Agriculture Final Demand Water 160 400 180 240 Industry: Electric Power 80 100 240 150 Agriculture 160 200 120 600 Other 400 300 60 The output matrix is X = (Round to two decimal places as needed.)
