can someone help me with this??? answer all/ most of the problems if you can and if possible show work in a way similar to #2 :)

look at the explanation for the work
3) b = 3
4) k = 8
5) v = -6
6) m = 7
step-by-step explanation:
1) 10(n + 10) = 160
10n + 100 = 160
-100 -100
10n = 60
/10 /10
n = 6 so correct
2) -114 = 6(x - 10)
-114 = 6x - 60
+60 +60
-54 = 6x
/6 /6
-9 = x so correct
3) -182 = 7(1 - 9b)
-182 = 7 - 63b
-7 -7
-189 = -63b
/-63 /-63
3 = b
4) 105 = 7(k + 7)
105 = 7k + 49
-49 -49
56 = 7k
/7 /7
8 = k
5) -8(v - 8) = 112
-8v + 64 = 112
-64 -64
-8v = 48
/-8 /-8
v = -6
6) 114 = 6(5 + 2m)
114 = 30 + 12m
-30 -30
84 = 12m
7 = m

Ya i could just need to know what type of math
