1362−271x/4

Step-by-step explanation:

STEP  1 :

Equation at the end of step 1

  (3/4 * (3x+6))-14*(5x-24)          

STEP  2 :

Simplify   3/4

Equation at the end of step  2 :

  3                

 (— • (3x + 6)) -  14 • (5x - 24)

:

Pulling out like terms

4.1     Pull out like factors :

  3x + 6  =   3 • (x + 2)  

Equation at the end of step

:

Rewriting the whole as an Equivalent Fraction

5.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  4  as the denominator :

                     14 • (5x - 24)     14 • (5x - 24) • 4

   14 • (5x - 24) =  ——————————————  =  ——————————————————

                           1                    4          

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 :

5.2       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:

9 • (x+2) - (14 • (5x-24) • 4)     1362 - 271x

——————————————————————————————  =  ———————————

              4                         4      

Final result :

 1362 - 271x

answer:

c. the third graph

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
