Answer:
4(x - 1) = 4x - 4
3x + 6 = 3(x + 2)
Step-by-step explanation:
The first equation is

We simplify to get;

This is not true, therefore this equation has no solution.
The second equation is

Combine like terms:



This has a unique solution.
The 3rd equation is

Group similar terms:

The 4th equation is :


This is always true. The equation has infinite solution.
The 5th equation is:

This also has infinite solution
The 6th equation is

It has a unique solution.
(3x + 4) / 4 = x - 3
3x + 4 = 4x - 12
-x + 4 = -12
-x = -16
x = 16
Check:
(3x + 4) / 4 = x - 3
(3*16 + 4) / 4 = 16 - 3
(48 + 4) / 4 = 13
52 / 4 = 13
13 = 13
