Rearrange:

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

                     (49/10)-(-(14/10)*n)>0 

Step by step solution :

Step  1  :

            7
 Simplify   —
            5

Equation at the end of step  1  :

  49           7
  —— -  (0 -  (— • n))  > 0 
  10           5

Step  2  :

            49
 Simplify   ——
            10

Equation at the end of step  2  :

  49    -7n
  —— -  ———  > 0 
  10     5 

Step  3  :

Calculating the Least Common Multiple :

 3.1    Find the Least Common Multiple

      The left denominator is :       10 

      The right denominator is :       5 

      Least Common Multiple:
      10 

Calculating Multipliers :

 3.2    Calculate multipliers for the two fractions


    Denote the Least Common Multiple by  L.C.M 
    Denote the Left Multiplier by  Left_M 
    Denote the Right Multiplier by  Right_M 
    Denote the Left Deniminator by  L_Deno 
    Denote the Right Multiplier by  R_Deno 

   Left_M = L.C.M / L_Deno = 1

   Right_M = L.C.M / R_Deno = 2

Making Equivalent Fractions :

 3.3      Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)²   and  (y²+y)/(y+1)³  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

   L. Mult. • L. Num.      49
   ——————————————————  =   ——
         L.C.M             10

   R. Mult. • R. Num.      -7n • 2
   ——————————————————  =   ———————
         L.C.M               10   

Adding fractions that have a common denominator :

 3.4       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:

 49 - (-7n • 2)     14n + 49
 ——————————————  =  ————————
       10              10   

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   14n + 49  =   7 • (2n + 7) 

Equation at the end of step  4  :

  7 • (2n + 7)
  ————————————  > 0 
       10     

Step  5  :

 5.1    Multiply both sides by  10 

 5.2    Divide both sides by  7 

 5.3    Divide both sides by  2  

      n+(7/2)  > 0

Solve Basic Inequality :

 5.4      Subtract  7/2  from both sides

            n > -7/2
