Answer 1:
e-(-73)= -27
e + 73 = -27
e = -27-73
e = -100
Answer 2:
-3+r = -52
r = -52 + 3
r = -49
Answer 3:
-6+f=13
f = 13 + 6
f = 19
Answer 4:
t+8=4
t = 4-8
t = -4
Answer 5:
m+9 = -12
m = -12-9
m = -21
Answer 6:
m-4=18
m = 18 + 4
m = 22
Answer 7:
m-12=25
m = 25 + 12
m = 37
Answer 8:
45=30+m
30 + m = 45
m = 45 - 30
m = 15
Answer 9:
x+7= -4
x = -4-7
x = -11
Answer 10:
a-(-98)= -2
a + 98 = -2
a = -2-98
a = -100

I'll help with a few. You should be able to get the hang of it after that.
1) e-(-73) = -27
Two negative signs cancel out and equal a positive
e + 73 = -27
Subtract 73 from each side
e + 73 - 73 = -27 - 73
e = -100
2) -3 + r = -52
Add 3 to each side
-3 + r + 3 = -52 + 3
r = -49
3) -6 + f = 13
Add 6 to each side
-6 + f + 6 = 13 + 6
f = 19
