                     Lesson 1

Problem:       Solve the expression for b.

                                                                     e = 5gb               where e=42 and g=12

Solution          Solve the expression for b.

                                                            Step 1:              e = 5gb

Solution          Values of e and g are given

                                                            Step 2:              e=42 and g=12

Solution          Replacing e with 42 and g with 12 and  substituting them in the given expression.

Step 3:               42 = 5x12b

                                                            Solution           Answer is: t =7/10

Step 4:                          

                                                            Complete

                                                            Try two practice problems:

Determine the value of the indicated variable.

A. 5j = 50m Find ‘m’. Given j=2

                                                  B.  g = (h+r+t)/3 Find ‘g’. Given h=13, r=3,t=4
