1. 86 + (-3x) = 62
Subtract 86 from both sides:
-3x = 62 - 86 → -3x = -24
Divide by -3:
x = (-24)/(-3) =
8
→ Match with
8
---
2. 71 + 3x = 86
Subtract 71 from both sides:
3x = 86 - 71 → 3x = 15
Divide by 3:
x = 15/3 =
5
→ Match with
5
---
3. 120 + (-11x) = 76
Subtract 120 from both sides:
-11x = 76 - 120 → -11x = -44
Divide by -11:
x = (-44)/(-11) =
4
→ Match with
4
---
4. 89 + (-9x) = 71
Subtract 89 from both sides:
-9x = 71 - 89 → -9x = -18
Divide by -9:
x = (-18)/(-9) =
2
→ Match with
2
---
5. 44 - 2x = 30
Subtract 44 from both sides:
-2x = 30 - 44 → -2x = -14
Divide by -2:
x = (-14)/(-2) =
7
→ Match with
7
---
6. 32 + 4x = 16
Subtract 32 from both sides:
4x = 16 - 32 → 4x = -16
Divide by 4:
x = -16/4 =
-4
→ Match with
-4
---
7. 15 - 3x = 45
Subtract 15 from both sides:
-3x = 45 - 15 → -3x = 30
Divide by -3:
x = 30 / (-3) =
-10
→ Match with
-10
---
8. 100 + 4x = 80
Subtract 100 from both sides:
4x = 80 - 100 → 4x = -20
Divide by 4:
x = -20/4 =
-5
→ Match with
-5
---
9. 40 + 2x = 36
Subtract 40 from both sides:
2x = 36 - 40 → 2x = -4
Divide by 2:
x = -4/2 =
-2
→ Match with
-2
---
10. 48 + 2x = 32
Subtract 48 from both sides:
2x = 32 - 48 → 2x = -16
Divide by 2:
x = -16/2 =
-8
→ Match with
-8
---
Final Answer:
1 → 8
2 → 5
3 → 4
4 → 2
5 → 7
6 → -4
7 → -10
8 → -5
9 → -2
10 → -8
