Systems of Linear Equations

1) Solve by the addition method. 3x + 2y = 14 3x - 2y = 10 2) Solve by the addition method 5x = 6y + 50 2y = 8 - 3x 3) Solve. Identify systems with no solution and systems with infinitely many solutions, using set notation to express their solution sets. 4) Can't type fractions, so

Problems 4.1 1, 2, 3, 6, 7, 8, 9, 11, 15 and 16. (page 147) I attached few pages description. See attached file for full problem description.

Please see the attached files for the fully formatted problems. 1. Given the equation below, find f(x) where y = f(x). 8y(6x - 7) - 12x(4y + 3) + 265 - 5(3x - y + 2) = 0. 2. Solve these linear equations for x, y, and z. 3x + 5y - 2z = 20; 4x - 10y -z = -25; x + y -z = 5 3. The value of y in Question 2 lies in the ran

4x+y=12 (1) x-y=8(2) 4x+y=12 x-y=8 5x/5 = 20/5 X=4 4(4) =y - 12 16+y = 12 Y =4 I think this would be an example of elimination method for solving a system of equations however I am unsure how it would transfer to substitution method thus I am needing assistance. I am needing this to be illustrated if you wi

Please help with the following problems. Provide step by step calculations. Find the slope of each line that has a slope x=5y Find an equation in the form y=ms +b (where possible) for each line. Through (3,-5) parallel to y= 4 Graph each linear equation defined as follows; 3x - 5y =15 Solve each system of equat

A) Find the inverse of: |2 1 1| |0 1 2| |2 2 1| b) Use it to solve the following system of equations: 2x1 + x2 + x3 = 4 x2 + 2x3 = 0 2x1 + 2x2 + x3 = 1.

Please help with the following problems. There are three methods to solving Linear Systems with two Equations. They are the Graph method, the Elimination method, and the Substitution method. When would you use each method? What makes each method better than the other methods?

Solve the following linear system using Gaussian elimination. Show work. 2y + z = 4 x+ y +z = 6 2x + y + z = 7 Solve the following linear system for x using Cramer's rule. Show work. 4x - y + z = -5 2x + 2y + 3z = 10 5x - 2y + 6z = 1

In your own words can you explain to me how inverses are used to solve linear systems?
