Evaluating Expressions Worksheet

                     Lesson 1

Problem:   Evaluate the equation 6x + 2 for the given values of x:

x	1	2	3
6x + 2	8	14	20

Solution    Find the value for every values of x

Step 1:

Solution    For x = 1; 6 + 2 = 8

Step 2:         

Solution    For x = 2; 12 + 2 = 14

Step 3:  

                                                            Solution     For x = 3; 18 + 2 = 20

Step 4:   

                                                            Solution     Put values in table:

Step 5:  

                                                            Solution     Answer:

Step 6:

Complete

X	1	2	3
x + 1	8	14	20

Try two practice problems:  

1.	Simplify: y + (2y)^2 + 2y^2 + 3y
2.	Evaluate the formula by substituting the given values for each variable: 6x + 2y for x = 3, y = 1
