Question

3/4x+2/5=4x-1/4x
solve plz
show work

Answer 1

Answer:

x=− 19/2 -9.500

Step-by-step explanation:

• step one
• Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    3/4*x+5-(1/4+1/4*x)=0

• simplify 1/4

   3        1  1

 ((—•x)+5)-(—+(—•x))  = 0

   4        4  4

• end of step one
• step 2 is to repeat the same thing as step one answer is also same as step one
• step 3

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:

1 + x                   x + 1

—————  =  —————

  4                         4  

   3               (x + 1)

•  ((— • x) +  5) -  ———————  = 0

   4                  4  

• send of step 3

• step 4
•                  3
•  Simplify   —            

                         4

•  3                           (x + 1)
•  ((— • x) +  5) -  ———————  = 0
•    4                             4  
•  5.1   Adding a whole to a fraction
• Rewrite the whole as a fraction using  4  as the denominator :
•             5              5 • 4
•    5 =  —  =  —————
•             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
• 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:
• 3x + 5 • 4                          3x + 20
• ——————————  =  ———————
•     4                                          4  

•  (3x + 20)                      (x + 1)
•  ————————— -  ———————  = 0
•      4                         4  
• 6.1       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:
• (3x+20) - ((x+1))                                      2x + 19
• —————————————————  =  ———————
•         4                                                           4  

•      2x + 19
•  ———————  = 0
•          4  

• 7.1    When a fraction equals zero ...
• Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
• Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
• Here's how:
•  2x+19
•  ————— • 4 = 0 • 4
•    4  
• Now, on the left hand side, the  4  cancels out the denominator, while, on the right hand side, zero times anything is still zero.
• The equation now takes the shape :
•   2x+19  = 0

• 7.2      Solve  :    2x+19 = 0
• Subtract  19  from both sides of the equation :
•                      2x = -19
• Divide both sides of the equation by 2:
•                     x = -19/2 = -9.500
