Find the value of x in:

1. 2x + 4 = 6x – 12 

2. 5x – 9 = 2x + 18 

3. 6x – 11 = 3 – x

4. 13 – 2x = 3x – 2 

5. 54x – 103 = -x + 7 

6. x/2 – 3 = 2x + 9 

7. 2x – 7 = x/3 + 93 

8. x/3 +1 = x/2 – 1 

Find x in terms of y:

1. 4x – 2y = 8 

2. 3x + 5y = 9 – y 

3. 7y – 4x = 14 + 3x 

4. 4x – 9 = 8y – 1 

5. 14x -8y + 5 = 2x + 4y -7 

6. 7x + 4y – 3 = 3x + 1
