Of course! Let’s solve each equation step by step to find the missing numbers. The goal is to make each equation true.

Left Column:
1.
14 – □ = 6
→ To find the missing number, subtract 6 from 14:
14 – 6 = 8
✔ So,
□ = 8
2.
□ – 10 = 7
→ Add 10 to both sides:
7 + 10 = 17
✔ So,
□ = 17
3.
13 = □ – 4
→ Add 4 to both sides:
13 + 4 = 17
✔ So,
□ = 17
4.
2 = □ – 17
→ Add 17 to both sides:
2 + 17 = 19
✔ So,
□ = 19
5.
9 = □ – 11
→ Add 11 to both sides:
9 + 11 = 20
✔ So,
□ = 20
6.
23 – □ = 14
→ Subtract 14 from 23:
23 – 14 = 9
✔ So,
□ = 9
7.
15 – □ = 13
→ Subtract 13 from 15:
15 – 13 = 2
✔ So,
□ = 2
---
Right Column:
8.
9 = □ – 9
→ Add 9 to both sides:
9 + 9 = 18
✔ So,
□ = 18
9.
12 = □ – 8
→ Add 8 to both sides:
12 + 8 = 20
✔ So,
□ = 20
10.
15 = □ – 5
→ Add 5 to both sides:
15 + 5 = 20
✔ So,
□ = 20
11.
□ – 8 = 7
→ Add 8 to both sides:
7 + 8 = 15
✔ So,
□ = 15
12.
16 – □ = 14
→ Subtract 14 from 16:
16 – 14 = 2
✔ So,
□ = 2
13.
3 = 19 – □
→ Subtract 3 from 19:
19 – 3 = 16
✔ So,
□ = 16
14.
□ = 17 – 9
→ Simply calculate:
17 – 9 = 8
✔ So,
□ = 8
