Alguém me ajuda por favor

Resolva as seguintes equações

1) 3x = 15

2) 2x = 14

3) 4x = -12

4) 7x = -21

5) 13x = 13

6) 9x = -9

7) 25x = 0

8) 35x = -105

9) 4x = 1

10) 21 = 3x

11) 84 = 6x

12) 6x = 2x + 16

13) 2x – 5 = x + 1

14) 2x + 3 = x + 4

15) 5x + 7 = 4x + 10

16) 4x – 10 = 2x + 2

17) 4x – 7 = 8x – 2

18) 2x + 1 = 4x – 7

19) 9x + 9 + 3x = 15

20) 16x – 1 = 12x + 3

21) 3x – 2 = 4x + 9

22) 5x -3 + x = 2x + 9

23) 17x – 7x = x + 18

24) x + x – 4 = 17 – 2x + 1

25) x + 2x + 3 – 5x = 4x – 9

26) 5x + 6x – 16 = 3x + 2x - 4

27) 5x + 4 = 3x – 2x + 4​
