Solving Equations With Graphing


Equations like 3x + 5 = 6x - 1 can be solved easily using a graphing utility. Just set each side equal to y.

y = 3x + 5

y = 6x - 1


Graph the two equations using a graphing utility and then find the point of intersection of the two lines. The x-coordinate of the point of intersection is the solution of the equation.

Solve the following equations by graphing.

1. 4x = 5x - 3

2. -3x + 1 = 2x - 14

3. -5x - 1 = 5x - 1

4. -x - 2 = -2x + 1

5. 3x + 4 = x - 6

6. 2x - 6 = -x + 24
