 = 8.  
 X -7 = 8 X -7 
2k - 10 = -56
2k - 10 + 10 = -56 + 10
2k = -46
2k / 2 = -46 / 2
k = -23

Take it slow ... one little step at a time:

                                             (2k - 10) / -7  =  8

Multiply each side by  -7 :      2k - 10         =  -56

Add  10  to each side:            2k                =  -46

Divide each side by  2 :           k                =  -23
