Answer:
k = - 50
Step-by-step explanation:
Given
k - 5 = k
Multiply through by 10 ( the LCM of 5 and 10 ) to clear the fractions
6k - 50 = 7k ( subtract 6k from both sides )
- 50 = k
Simple, all you want to do is subtract. 7-2=5; and denominators are not subtracted thus it would be 5/8. And that is the simplest form already 5/8.
