Reformatting the input :

Changes made to your input should not affect the solution:

(1): "6.3" was replaced by "(63/10)". 2 more similar replacement(s)

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

                     -(91/10)-(d-(63/10))<0 

Step by step solution :

Step  1  :

            63
 Simplify   ——
            10

Equation at the end of step  1  :

        91           63
  (0 -  ——) -  (d -  ——)  < 0 
        10           10

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  10  as the denominator :

          d     d • 10
     d =  —  =  ——————
          1       10  

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:

 d • 10 - (63)     10d - 63
 —————————————  =  ————————
      10              10   

Equation at the end of step  2  :

        91     (10d - 63)
  (0 -  ——) -  ——————————  < 0 
        10         10    

Step  3  :

            91
 Simplify   ——
            10

Equation at the end of step  3  :

        91     (10d - 63)
  (0 -  ——) -  ——————————  < 0 
        10         10    

Step  4  :

Adding fractions which have a common denominator :

 4.1       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:

 -91 - ((10d-63))     -10d - 28
 ————————————————  =  —————————
        10               10    

Step  5  :

Pulling out like terms :

 5.1     Pull out like factors :

   -10d - 28  =   -2 • (5d + 14) 

Equation at the end of step  5  :

  -2 • (5d + 14)
  ——————————————  < 0 
        10      

Step  6  :

 6.1    Multiply both sides by  10 

 6.2    Divide both sides by  -2 

Remember to flip the inequality sign:

 6.3    Divide both sides by  5  

      d+(14/5)  > 0

Solve Basic Inequality :

 6.4      Subtract  14/5  from both sides

            d > -14/5
