Solve the system of equations by substituting the value expression for y from the second equation into the first equation. If it's easier, you can start by solving an equation for To either equation to find the corresponding (The two equations represent the same line.) The lines intersect at infinitely many points. Solving using the substitution method will yield one of three results: a single value for each variable within the system (indicating one solution), an untrue statement (indicating no solutions), or a true statement (indicating. Then replace that variable in the other equation with. Aubrey is using the substitution method to solve the following system of equations: y x 21. The lines intersect at exactly one point. To solve a system of equations by substitution, solve one of the equations for a variable, for example x. , the graph of a system of two equations is a pair of lines in the plane. Is just a set of two or more linear equations. Solving Systems of Linear Equations Using Substitution
