Using Substitution Solve the following system of equations: y x2 6x 9 and y x 5. Step 1 Solve y x 5 for y. y x x 5 x Subtract xfrom both sides. y 5 x Step 2 Write a single equation containing only one variable. y x2 6x 9 5 x xx2 6x 9 Substitute 5 for y. 5 x (5 x) x2 6x 9 (5 x) Subtract 5 xfrom both sides. 0 x2 5x 4 Step 3 Factor and solve for x. 0 (x 4)(x 1) Factor. There are two TI-Nspire functions for solving systems of equations: linSolve() and solve() (or cSolve()). solve() is a general-purpose function for solving single equations and systems of equations, both linear and non-linear. cSolve() is a version of solve() that works with complex values. linSolve() is a special-purpose func-

The main idea behind solving systems with the substitution method is to choose one of the equations, solve it for one of the variables, and plug the result into the other equation. This way, we obtain an equation with one variable, which we can easily solve. Once we have found the value of one variable, we utilize it to find the other variable.
