Answer:

k= -0.2

Step-by-step explanation:

3+2(5k-3)=7              (original)

3+10k-6=7                 (distribute 2 in (5k-3))

9+10k=7                    (combine like terms 3+-6)

10k=-2                       (subtract 9 on both sides to isolate k)

k=-0.2                       (divide 10 on both sides to get you're answer/isolate k)
