I need some help in understanding what I did wrong with this problem. According to the picture, there are two sectors of the U.S. economy. One of them is audio, video, and communication equipment, while the other has electronic components and accessories. This problem has something to do with finding the vectors by using the formula (I-A)D.

MY NOTES Communication Equipment Two sectors of the U.S. economy are (1) audio, video, and communication equipment and (2) electronic components and accessories. Suppose in 1998, the input- output table involving these two sectors was as follows (all figures are in millions of dollars). To Equipment Components Equipment 5,800 500 From Components 26,000 28,000 Total Output 90,000 140,000 Determine the production levels (in dollars) necessary in these two sectors to meet an external demand for $79,000 million of communication equipment and $88,000 million of electronic components. Round answers to two significant digits. equipment $ X millions components $ x millions
