Sagot :

Answer:

846x + 2123

 —————

     423  

Step-by-step explanation:

STEP

1

:

            8

Simplify   ———

           423

Equation at the end of step

1

:

              8

 (2x + 5) +  ———

             423

STEP

2

:

Rewriting the whole as an Equivalent Fraction

2.1   Adding a fraction to a whole

Rewrite the whole as a fraction using  423  as the denominator :

              2x + 5     (2x + 5) • 423

    2x + 5 =  ——————  =  ——————————————

                1             423      

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

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

(2x+5) • 423 + 8     846x + 2123

————————————————  =  ———————————

      423                423    

Final result :

  846x + 2123

 ———————————

     423
