- Writing Consider the system of linear equations in x and y. a1x+b1y=c1a2x+b2y=c2a3x+b3y=c3 Describe the graphs of these three equations in the xy-plane when the system has a exactly one solution, b infinitely many solutions, and c no solution.arrow_forwardDiscovery In Exercises 91 and 92, sketch the lines represented by the system of equations. Then use Gaussian elimination to solve the system. At each step of the elimination process, sketch the corresponding lines. What do you observe about the lines? 2x3y=74x+6y=14arrow_forwardSKILL BIULDIND EXERCISES What Is the Solution For a certain system of two linear equations in two unknowns, the graphs are distinct parallel lines. What can you conclude about the solution of the system of equations?arrow_forward
- Coefficient Design In Exercises 51 and 52, find values of a, b, and c if possible such that the system of linear equation has a a unique solution, b no solution, and c infinitely many solutions. x+y=2y+z=2x+z=2ax+by+cz=0arrow_forwardSolving a system of equation in three variables Find the complete solution of the linear system, or show that it is inconsistent. {xy+z=0y+2z=2x+yz=2}arrow_forward
