Question

6) 7(-3r – 5) – 2(8r + 2) = 35

8) –5b – 13 = -3 – 3b
10) 34 – 7k=-6(4 + 6k)
I need the answers

Answer 1

6)
7(-3-5)-2(8r+2) = 35
-21-35-16r-4 = 35
-16r = 35+21+35+4
-16r = 95
r = 95/-16
r = -5 15/16
8)
-5b-13 = -3-3b
-5b+3b = -3+13
-2b = 10
b = 10/-2
b = -5
10)
34 - 7k = -6(4+6k)
34 - 7k = -24 -36k
-7k + 36k = -24 -34
29k = -58
k = -58/29
k = -2

Answer 2

6) r=-2

8) b=-5

10) k=-2
