selesaikan persamaan berikut! 1.2x-7=24 2.10-3x=-18 3.5x+7=2x+28 4.19+3x=7x-11 5.4x-3+x=24-3x Tolong jawab,pliss

1. 2x - 7 = 24
2x = 24 + 7
2x = 31
x = 31/2

2. 10 - 3x = -18
-3x = -18 - 10
-3x = -28
x = 28/3

3. 5x + 7 = 2x + 28
5x - 2x = 28 - 7
3x = 21
x = 21/3
x = 7

4. 19 + 3x = 7x - 11
3x - 7x = -11 - 19
-4x = -30
x = 30/4

5. 4x -3+x = 24 - 3x
4x + 3x + x = 24 + 3
8x = 27
x = 27/8
