Answer 2

To solve these equations, we need to isolate the variable 'x' on one side of the equation. We do this by performing the same operation on both sides of the equation until 'x' is alone on one side. Let's go through each equation step by step:

13. -8 + x = -1

Step 1: Add 8 to both sides. x = -1 + 8 x = 7

14. -4 + x = 5

Step 1: Add 4 to both sides. x = 5 + 4 x = 9

15. x + 6 = -3

Step 1: Subtract 6 from both sides. x = -3 - 6 x = -9

16. -6 + x = 4

Step 1: Add 6 to both sides. x = 4 + 6 x = 10

17. -2 + x = 8

Step 1: Add 2 to both sides. x = 8 + 2 x = 10

18. x + 7 = -3

Step 1: Subtract 7 from both sides. x = -3 - 7 x = -10

19. x + 8 = -2

Step 1: Subtract 8 from both sides. x = -2 - 8 x = -10

20. x + 3 = -8

Step 1: Subtract 3 from both sides. x = -8 - 3 x = -11

21. -5 + x = 7

Step 1: Add 5 to both sides. x = 7 + 5 x = 12

22. -9 + x = 4

Step 1: Add 9 to both sides. x = 4 + 9 x = 13

23. 9 + x = -10

Step 1: Subtract 9 from both sides. x = -10 - 9 x = -19

24. 2 + x = 1

Step 1: Subtract 2 from both sides. x = 1 - 2 x = -1

So, the solutions for each equation are:

13. x = 7
14. x = 9
15. x = -9
16. x = 10
17. x = 10
18. x = -10
19. x = -10
20. x = -11
21. x = 12
22. x = 13
23. x = -19
24. x = -1
