Subtracting 3 from both sides gives 2x = 12. Dividing by 2 gives x = 6.

Subtracting 5 from both sides gives 3x = 15. Dividing by 3 gives x = 5.

Subtracting 4 from both sides gives 2x = 12. Dividing by 2 gives x = 6.

Subtracting 7 from both sides gives 3x = 15. Dividing by 3 gives x = 5.

Adding 7 to both sides gives 3x = 9. Dividing by 3 gives x = 3.

Expanding both sides gives 4x - 8 = 3x + 3. Subtract 3x from both sides: x - 8 = 3. Adding 8 gives x = 11.

Adding 3 to both sides gives 5x = 5. Dividing by 5 gives x = 1.
