Hey! Sorry about your misunderstanding of your work, Allow me to help :)
Let's turn that phrase into an equation.
Negative K ( - k) over five ( /5 ) equals ( = ) seven (7) over five ( /5)
Let's put that together.
- k/5 = 7/5
To solve, we need to get rid of the fraction by getting rid of the denominator, in this case, the denominator for both sides is 5. Multiply each side by 5 to cancel out the 5. We get :
- k = 7
Now we need to get rid of that negative sign next to k, so what we do is divide each side by -1 so we can cancel out that negative 1 next to k.
Our Final answer is k = -7 .
