STEP  5 :

Adding fractions which have a common denominator :

5.1       Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

   49y - (26x)           49y - 26x

———————  =  ———————

         5                         5    

Equation at the end of step  5 :

  (49y - 26x)        34y       36x

 (—————— -  ———) +  ———

       5                   5             5  

STEP  6 :

Adding fractions which have a common denominator :

6.1       Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(49y-26x) - (34y)           15y - 26x

—————————  =  —————————

        5                              5    

Equation at the end of step  6 :

 (15y - 26x)          36x

 —————— +  ———

      5                    5  

STEP  7 :

Adding fractions which have a common denominator :

7.1       Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(15y-26x) + 36x     15y + 10x

———————    =  —————

       5                          5    

STEP  8 :

Pulling out like terms :

8.1     Pull out like factors :

  15y + 10x  =   5 • (3y + 2x)

b) 36
