Answer:

-16.3  ≥  q

Step-by-step explanation:

–5.3 ≥ 6.7 + 4.3 + q

Combine like terms

–5.3 ≥ 11 + q

Subtract 11 from each side

–5.3-11 ≥ 11-11 + q

-16.3  ≥  q

Answer:    q ≤ -163/10

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "4.3" was replaced by "(43/10)". 3 more similar replacement(s)

Rearrange:

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

               -(53/10)-((67/10)+(43/10)+q)≥0  

Step by step solution :

Step  1  :

           43

Simplify   ——

           10

Equation at the end of step  1  :

    53    67 43

 (0-——)-((——+——)+q)  ≥ 0  

    10    10 10

Step  2  :

           67

Simplify   ——

           10

Equation at the end of step  2  :

       53       67    43      

 (0 -  ——) -  ((—— +  ——) +  q)  ≥ 0  

       10       10    10      

Step  3  :

Adding fractions which have a common denominator :

3.1       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:

67 + 43     11

———————  =  ——

  10        1  

Equation at the end of step  3  :

       53      11    

 (0 -  ——) -  (—— +  q)  ≥ 0  

       10      1      

Step  4  :

           53

Simplify   ——

           10

Equation at the end of step  4  :

       53      

 (0 -  ——) -  (q + 11)  ≥ 0  

       10      

Step  5  :

Rewriting the whole as an Equivalent Fraction :

5.1   Subtracting a whole from a fraction

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

             q + 11     (q + 11) • 10

   q + 11 =  ——————  =  —————————————

               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 :

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:

-53 - ((q+11) • 10)     -10q - 163

———————————————————  =  ——————————

        10                  10    

Step  6  :

Pulling out like terms :

6.1     Pull out like factors :

  -10q - 163  =   -1 • (10q + 163)  

Equation at the end of step  6  :

 -10q - 163

 ——————————  ≥ 0  

     10    

Step  7  :

7.1    Multiply both sides by  10  

7.2    Multiply both sides by (-1)

Flip the inequality sign since you are multiplying by a negative number

     10q+163  ≤ 0

7.3    Divide both sides by  10  

     q+(163/10)  ≤ 0
