6 +2х = 4х – 30;
5х+ 3 = 4х +22;
2 + 2х = х +24;
5 + 7х =26 + 6х;

Answer 1

9x - 1 = 8x +  7
9x - 8x = 1 + 7
x = 8

4x - 6 = 2x + 12
4x - 2x = 12 + 6
2x = 18
x = 9

3x + 3 = 2x + 13
3x - 2x = 13 - 3
x = 10

9 - 3x = 20 - 4x
-3x + 4x = 20 - 9
x = 11

7x - 1 = 5x + 23
7x - 5x = 23 + 1
2x = 24
x = 12

2 - 3x = 28 - 5x
-3x + 5x = 28 - 2
2x = 26
x = 13

6x + 3 = 5x + 17
6x - 5x = 17 - 3
x = 14

8x - 10 = 6x + 20
8x - 6x = 20 + 10
2x = 30
x = 15

17x - 1 = 15 + 16x
17x - 16x = 15 + 1
x = 16

19 + 3x = 5x - 15
5x - 3x = 19 + 15
2x = 34
x = 17

6 + 2x = 4x - 30
2x - 4x = -30 - 6
-2x = -36
x = 18

5x + 3 = 4x + 22
5x - 4x = 22 - 3
x = 19

2 + 2x = x + 24
2x - x = 24 - 2
x = 22

5 + 7x = 26 + 6x
7x - 6x = 26 - 5
x = 21
