6x + 30 - 5x = 25

6x - 5x = 25 - 30

x = - 5

x = - 5

6x + 30 - 5x = 25

6( - 5) + 30 - 5( - 5) = 25 - 30 + 30 + 25 = 25

25 = 25

.

X - 4 - 3x = - 10 + 6

x - 3x - 4 = - 4 - 2x = - 4 + 4 - 2x = 0

x = 0

x = 0

x - 4 - 3x = - 10 + 6

0 - 4 - 3(0) = - 4 - 4 - 0 = - 4 - 4 = - 4

.

3x + 2x = 8x - 15

5x = 8x - 15

5x - 8x = - 15 - 3x = - 15

x = - 15 / - 3

x = 5

x = 5

3x + 2x = 8x - 15

3(5) + 2(5) = 8(5) - 15

15 + 10 = 40 - 15

25 = 25

.

- 3x + 9 = - 3x2x - 8

.

- x - 3 - 5x = - 27 - x - 5x = - 27 + 3 - 6x = - 24

x = - 24 / - 6

x = 4

x = 4 - x - 3 - 5x = 27 - (4) - 3 - 5(4) = 27 - 4 - 3 - 20 = 27 - 27 = - 27

.

2x - 6 = 3x - 36 + x

2x - 6 = 3x + x - 36

2x - 6 = 4x - 36

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

x = - 30 / - 2

x = 15

x = 15

2x - 6 = 3x - 36 + x

2(15) - 6 = 3(15) - 36 + 15

30 - 6 = 45 - 21

24 = 24.
