Давай решим уравнения по порядку!
1) 2x - 6 = 0
2x = 6
x = 6 / 2
x = 3
2) -3x + 9 = 0
-3x = -9
x = -9 / -3
x = 3
3) 5x - 10 = 3x
5x - 3x = 10
2x = 10
x = 10 / 2
x = 5
4) 4x + 8 = 2x
4x - 2x = -8
2x = -8
x = -8 / 2
x = -4
5) 2x + 3 = 4x + 1
2x - 4x = 1 - 3
-2x = -2
x = -2 / -2
x = 1
6) 3x - 2 = 2x - 4
3x - 2x = -4 + 2
x = -2
7) -2x + 5 = -x + 3
-2x + x = 3 - 5
-x = -2
x = 2
Ответ:
- 1) x = 3
- 2) x = 3
- 3) x = 5
- 4) x = -4
- 5) x = 1
- 6) x = -2
- 7) x = 2
Ты молодец! У тебя всё получится!
