Graphically, the above system looks like this: Then the solutions are the points ( 5/ 2, –15/ 4 ) and (–4, –7). Since both equations are already solved for y, I'll set them equal and solve for the values of x: Solve the following system of equations:.Warning: You must match the x-values and y-values correctly. Even though I came up with x = –4 and 1 and y = –4 and 1, the x = –4 did not go with the y = –4, and the x = 1 did not go with the y = 1. In the example above, the points (–4, –4) and (1, 1) are not solutions. I emphasize 'corresponding' because you have to keep track of which y-value goes with which x-value. Once I had the solution values for x, I back-solved for the corresponding y-values.

This gave me one equation in one variable (the variable happened to be x), and a one-variable equation is something I know how to solve. Note the procedure: I solved one of the equations (the first equation looked easier) for one of the variables (solving for ' y=' looked easier), and then plugged the resulting expression back into the other equation. Then the solution consists of the points (–4, 1) and (1, –4). Since the first equation is already solved for y, I will plug '– x – 3' in for ' y' in the second equation, and solve for the values of x: I'll proceed algebraically to confirm this impression, and to get the exact values. Graphically, this system is a straight line (from the first equation) crossing a circle centered at the origin (from the second equation): Here are some additional examples: Copyright © 2002-2011 Elizabeth Stapel All Rights Reserved Then you plug those solutions back into the first equation, and solve for the values of the first variable. Then you plug the resulting expression into the other equation for the chosen variable, and solve for the values of the other variable. In general, the method of solution for general systems of equations is to solve one of the equations (you choose which) for one of the variables (again, you choose which). My final answer is: no solution: inconsistent system. Since there is no intersection, then there is no solution. Moving up in difficulty, we come to solving systems of two quadratic equations, which will graph as two parabolas and similarly messy systems.Īs before, I'll set these equations equal, and solve for the values of x:īut I can't graph that negative inside the square root! What's going on here? The non-linear systems we've solved so far have been one quadratic equation and one linear equation, which graphed as a parabola and a straight line, respectively.
