To solve the first equation for k:

1.3 = 4(k + 2)
1.3 = 4k + 8
Subtract 8 from both sides:
-6.7 = 4k
Divide by 4:
k = -1.675

To solve the second equation for c:

5(c + 5) = -7
5c + 25 = -7
Subtract 25 from both sides:
5c = -32
Divide by 5:
c = -6.4

Therefore, the solutions are:
k = -1.675
c = -6.4
