Explanation Procedure used: Solving linear systems by Addition: (1) If necessary, rewrite both equation in the form of A x + B y = C . (2) If necessary, multiply either equation or both equation by appropriate nonzero numbers so that the sum of the x- coefficient or the sum of the y- coefficients is 0. (3) Add the equation in step 2. The sum is an equation in one variable. (4) Solve the equation in one variable. (5) Back-substitute the value found in step 4 either of the given equations and solve for the other variable. (6) Check the solution in either of the original equations. Definition used: Inconsistent : In solving a system of equations and it produce a false statement, then the equation is said to be inconsistent. The inconsistent system of equations has no solution. Calculation: Consider the given equations. 2 y = 3 x + 5 (1) 2 y = 3 x − 7 (2) By using the above procedure, solve the system of equations. Step 1: Let eliminate the term y. Since the coefficients of y term in both equations are same, multiply the equation (2) by –1. That is, − 2 y = − 3 x + 7

2. Use Broyden's method to solve the nonlinear system x² + y²+sin(x + y) x+y+cos(xy) = a = = 5 where a is the number formed by the first two digits of your SUID. Try at least two different starting points (or more, if needed to find a solution). Report the outcome of running the method for each starting point. Was the root you found always the same?

The correct answer is Ccould you show me how to do it by finding a0 and and akas well as setting up the piecewise function and integrating

This is an example only. What can be a simialr equation with differnet numbers using logs and can have a mistake in one of the steps and what will be the correct way to solve it. Thanks
