1)

–5x + 3 = x – 3

3 + 3 = x + 5x

6 = 6x

6/6 = x

1 = x

x = 1

2)

–3x + 4 = 4 – x

4 – 4 = –x + 3x

0 = 2x

0 = x

x = 0

3)

–3x + 1 = 2x – 9

1 + 9 = 2x + 3x

10 = 5x

10/5 = x

2 = x

x = 2

4)

10 + 2x = 12 + 3x

10 – 12 = 3x – 2x

–2 = x

x = –2

5)

9x – 3 = 5x + 9

9x – 5x = 9 + 3

4x = 12

x = 12/4

x = 3

6)

6 + 2x = 5x – 3

6 + 3 = 5x – 2x

9 = 3x

9/3 = x

3 = x

x = 3

7)

2x + 5 = 4x – 3

5 + 3 = 4x – 2x

8 = 2x

8/2 = x

4 = x

x = 4

8)

4x – 1 = 2x – 15

4x – 2x = –15 + 1

2x = –14

x = –14/2

x = –7
