systems with three variables - 960×720
{"Image DocumentName": "EXAMPLE 3 Solve a three-variable system with many solutions. STEP 3.", "Image ImageDescription": "Describe the solutions of the system. One way to do this is to divide new Equation 1 by 2 to get x + y = 4, or y = \u2013x + 4. Substituting this into original Equation 1 produces z = 0. So, any ordered triple of the form (x, \u2013x + 4, 0) is a solution of the system.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
