Question

Medal!

Part of Part A is solved.

A system of equations is shown below:

-3x + 7y = -16
-9x + 5y = 16

Part A: Create an equivalent system of equations by replacing one equation with the sum of that equation and a multiple of the other. Show the steps to do this. (6 points)

Part B: Show that the equivalent system has the same solution as the original system of equations. (4 points)

Answer 1

Solved part of Part A:

-3x + 7y = -16
-3 * 2 = -6
7 * 2 = 14
-16 * 2 = -32

New system of equations-
-6x + 14y = -32
-9x + 5y = 16
