Let’s solve each equation one by one. We’ll use the same method for all:
Step 1: Get rid of the number being added or subtracted (by doing the opposite).
Step 2: Then divide or multiply to get x alone.
---
1. 2x + 6 = 15
Subtract 6 from both sides:
2x = 9
Divide by 2:
x = 4.5
✔
2. 2x – 4 = 1
Add 4 to both sides:
2x = 5
Divide by 2:
x = 2.5
✔
3. 6x – 10 = 5
Add 10 to both sides:
6x = 15
Divide by 6:
x = 2.5
✔
4. 10 = 5x – 9
Add 9 to both sides:
19 = 5x
Divide by 5:
x = 3.8
✔
5. 5x – 2 = 2
Add 2 to both sides:
5x = 4
Divide by 5:
x = 0.8
✔
6. 6 = 2x – 5
Add 5 to both sides:
11 = 2x
Divide by 2:
x = 5.5
✔
7. 6 + 2x = 13
Subtract 6 from both sides:
2x = 7
Divide by 2:
x = 3.5
✔
8. 2x – 5 = 8
Add 5 to both sides:
2x = 13
Divide by 2:
x = 6.5
✔
All answers checked and correct.
Final Answer:
x = 4.5, 2.5, 2.5, 3.8, 0.8, 5.5, 3.5, 6.5
