How would you know if a linear system has a solution?

WebYou can use ELIMINATION when you ALREADY KNOW that your lines have a solution. For example, if you see a picture. If you find y=mx+b and determine that the lines ARE running parallel to each other, then there is no need to try and solve the equations, THERE IS NO SOLUTION. So, either one works. WebExample 1: Using Elimination To Show A Linear System Has Infinite Solutions Let’s say we want to solve the following system of linear equations: 2x + 4y = 3 -6x – 12y = -9 We will use elimination to solve.
