Question

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

Answer 1

here is your answer

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
