Let’s solve each equation one by one. These are all “one-step” equations, which means we only need to do
one thing (add or subtract) to both sides to find the value of x.
We’ll go in order from 1 to 24.

1)
x + 4 = -1
Subtract 4 from both sides:
x = -1 - 4 → x =
-5
2)
x - 3 = +5
Add 3 to both sides:
x = 5 + 3 → x =
+8
3)
x - 2 = -3
Add 2 to both sides:
x = -3 + 2 → x =
-1
4)
x + 7 = +3
Subtract 7 from both sides:
x = 3 - 7 → x =
-4
5)
x - 6 = +1
Add 6 to both sides:
x = 1 + 6 → x =
+7
6)
x - 2 = +12
Add 2 to both sides:
x = 12 + 2 → x =
+14
7)
x + 2 = +8
Subtract 2 from both sides:
x = 8 - 2 → x =
+6
8)
x - 3 = -1
Add 3 to both sides:
x = -1 + 3 → x =
+2
9)
x + 5 = +3
Subtract 5 from both sides:
x = 3 - 5 → x =
-2
10)
x + 4 = -4
Subtract 4 from both sides:
x = -4 - 4 → x =
-8
11)
x + 3 = +4
Subtract 3 from both sides:
x = 4 - 3 → x =
+1
12)
x + 9 = +9
Subtract 9 from both sides:
x = 9 - 9 → x =
0
13)
x - 8 = +4
Add 8 to both sides:
x = 4 + 8 → x =
+12
14)
x - 4 = -1
Add 4 to both sides:
x = -1 + 4 → x =
+3
15)
x - 3 = +1
Add 3 to both sides:
x = 1 + 3 → x =
+4
16)
x - 3 = -7
Add 3 to both sides:
x = -7 + 3 → x =
-4
17)
x - 8 = +2
Add 8 to both sides:
x = 2 + 8 → x =
+10
18)
x + 9 = +1
Subtract 9 from both sides:
x = 1 - 9 → x =
-8
19)
x + 2 = -6
Subtract 2 from both sides:
x = -6 - 2 → x =
-8
20)
x - 1 = -5
Add 1 to both sides:
x = -5 + 1 → x =
-4
21)
x - 1 = +5
Add 1 to both sides:
x = 5 + 1 → x =
+6
22)
x + 6 = +4
Subtract 6 from both sides:
x = 4 - 6 → x =
-2
23)
x + 4 = -7
Subtract 4 from both sides:
x = -7 - 4 → x =
-11
24)
x - 2 = +3
Add 2 to both sides:
x = 3 + 2 → x =
+5
