Systems of Linear Equations-Review

Which method is best? Place the system of equations under the best method to use to solve the problem. Substitution Method y = 2x - 1 and 3x + 4y = 12 5x - 2y = 15 and x = -2y - 7 Elimination Method 3x + y = 14 and 4x - y = 21 x + y = 3 and 2x - y = 0 Solve the systems of equations and match them with their appropriate number of solutions -3x+3y=4 and -x+y=3 No solution 2x+8y=6 and -5x-20y=-15 Infinitely many solutions y=5x-7 and -3x-2y=-12 One solution Error Analysis: Find and describe the error in the problem above. System of Equations - Graphing Use the graph to find the solution to the following system of equations:y = -2x - 4 y = 3x + 1 Solution to a System of Equations Write the coordinates to the solution to this system of equations. (1, 3) Solve the following system of equations:x = 2y - 184x + y = 13 (2, -5) (-2, 3) (2, 5) (-2, -5) What is the correct first step to solve this system of equations?4x - 3y = -102x + 3y = 4 add the two equations together subtract the two equations multiply the second equation by 3 multiply the first equation by 4 Solve the following system of equations:2x + y = 73x - 4y = 5 (-1, 9) (-3, -1) (7, 4) (3, 1)
