Consider a system of linear equations for price P and production Q as follows: 5P+Q=68, and -3P+Q=-10. Its coefficient matrix is given by \left[\begin{array}{ccc} 5&1&68 \\ -3&1&-10\end{array}\right] . Now, use forward elimination method to obtain its upper triangular form \left[\begin{array}{ccc} 1&a&13.6 \\ 0&1&19.25\end{array}\right] where a is some value you need to work out. So, what is the value of a rounded to 2 decimal places? Question 5 Answer a. 0.20 b. 0.00 c. 19.25 d. none of the others e. 0.36
