Simplify Expressions Worksheet

                     Lesson 1

Problem:     Simplify: 10x+11x.

Solution      Terms having the same powers of variables are like terms; otherwise, they are

Step 1:          unlike terms.        

10x + 11x   

Solution      The sum of several like terms is another like term whose coefficient is the sum of those

                                       Step 2:          like terms.

x(10+11)        

Solution     To subtract an expression from another, we change the sign of each term of the expression

Step 3:      to be subtracted and then add expressions.

x(21)

                                       Solution Collect like terms to find equivalent expression

                                       Step 4: 

                                       Solution      Answer is: 21t

   Step 5:             

                                       Complete
