9.8y - 5.2 x - 6.8y + 7.2 x

3y + 2x

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "7.2" was replaced by "(72/10)". 4 more similar replacement(s)

STEP  1 :

Simplify  36/5

Equation at the end of step  1 :

    98          52         68         36

 (((——•y)-(——•x))-(——•y))+(——•x)

    10           10           10          5  

STEP  2 :

Simplify   34/5

Equation at the end of step  2 :

    98          52          34           36x

 (((——•y)-(——•x))-(——•y))+———

    10           10           5           5  

STEP  3 :

Simplify   26/5

Equation at the end of step  3 :

    98           26      34y      36x

 (((——•y)-(——•x))-———)+———

    10            5         5           5  

STEP  4 :

Simplify   49/5

Equation at the end of step  4 :

      49           26x          34y       36x

 (((—— • y) -  ———) -  ———) +  ———

     5               5              5           5  

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)

after simplifying it i got: -36.25 as my answer. hope that !
