When you distribute the y, you get 4y 2 + 3y = 6. Section 5.1 Solving Systems of Linear Equations by Graphing 235 Writing a System of Linear Equations Work with a partner. you can keep zooming in in order to get to get a Solving a system of equations can become messy after a while. We’ve already had experience graphing equations with the graphing calculator. Because this equation is quadratic, you must get 0 on one side, so subtract the 6 from both sides to get 4y 2 + 3y – 6 = 0. . x squared minus three is giving you the same y as Note the "=" signs are already put in for you.
