Question

1/3k+80=1/2k+120 k=??

Answer 1

Answer:

here is your answer

Step-by-step explanation:

k = -240

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

1/3*k+80-(1/2*k+120)=0

Simplify:

1/2

    1                1

 ((—•k)+80)-((—•k)+120)  = 0

    3                2

Rewrite the whole as a fraction using  2  as the denominator :

             120             120 • 2

 120 =  ———  =  ———————

                1                     2  

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
