Question

solve and check 5/k? -6? = -3

Answer 1

5/k – 6 + 6 = 3 + 6
5/k = 3
5 /k • k = 3k
5/-3 = 3k / -3
5/3 = k

The answer is C) k = 5/3

Answer 2

remember you can do ANYTHING to an equaiton aslong as you do it to BOTH SIDES

5/k-6=-3
add 6 to both sides
5/k+6-6=-3+6
5/k+0=3
5/k=3
times k both sides
5k/k=3k
5(k/k)=3k
5=3k
divide both sides by 3
5/3=k

check

5/(5/3)-6=-3
15/5-6=-3
3-6=-3
-3=-3

true

k=5/3
