Answer:
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
