Answer 2

It looks like you've provided a series of equations with "x" as the variable. Let's solve them one by one:

1. 5x = 30 - 5 5x = 25 x = 25 / 5 x = 5

2. 6x = 30 + 6 6x = 36 x = 36 / 6 x = 6

3. x * 7 = 4 + 45 7x = 49 x = 49 / 7 x = 7

4. 37 - x = 21 / 7 37 - x = 3 -x = 3 - 37 -x = -34 x = 34

5. x + 7 = 28 / 4 x + 7 = 7 x = 7 - 7 x = 0

6. 7x * 70 / 10 = 7x 7x = 7x

7. 7x = 0 x = 0

8. x + 5 = 3 + 17 x + 5 = 20 x = 20 - 5 x = 15

9. x * 5 = 60 - 20 5x = 40 x = 40 / 5 x = 8

10. x * 4 = 20 + 20 4x = 40 x = 40 / 4 x = 10

11. x * 7 = 58 - 30 7x = 28 x = 28 / 7 x = 4

12. 6x = 50 - 20 6x = 30 x = 30 / 6 x = 5

So, the solutions for the equations are as follows:

1. x = 5
2. x = 6
3. x = 7
4. x = 34
5. x = 0
6. x can be any value (infinite solutions)
7. x = 0
8. x = 15
9. x = 8
10. x = 10
11. x = 4
12. x = 5
