Answer 2

To solve these equations, I'll isolate the variable on one side of the equation:

1. 10 + C = 90 C = 90 - 10 C = 80

2. a - 5 = 45 a = 45 + 5 a = 50

3. 40 + x = 80 x = 80 - 40 x = 40

4. C - 20 = 6 C = 6 + 20 C = 26

5. 24 - a = 12 a = 24 - 12 a = 12

6. a + 15 = 100 a = 100 - 15 a = 85

7. a - 10 = 10 a = 10 + 10 a = 20

8. 9 + x = 16 x = 16 - 9 x = 7

9. C - 8 = 18 C = 18 + 8 C = 26

10. 89 - x = 89 x = 89 - 89 x = 0

11. C + 30 = 70 C = 70 - 30 C = 40

12. y - 6 = 12 y = 12 + 6 y = 18

13. 63 - C = 0 C = 63 - 0 C = 63

14. B + 7 = 23 B = 23 - 7 B = 16

I hope this helps!
