Solving Equations
The graphing calculator can be easily used to
solve and/or check algebraic equations.
Example 1:
Solve for x:
4x + 1 = 9




Example 2: Solve for x: 2x + 4 = 5x  2




Example 3: Solve for x: x^{2 }+ x = x^{2}  2x + 6




Example 4:. Solve for x: 15x  3(3x + 4) = 6. Choose the correct value for x.
