Cannot be determined.

Given x + 5x + 4 = 3(2x - 1)

Combine like terms on left-hand side of the equation, and distribute 3 into (2x -1):

6x + 4 = 6x - 3

Subtract from both sides:

6x + 4 - 4 = 6x - 3 - 4

6x = 6x - 7

Subtract 6x from both sides:

6x - 6x = 6x - 7 - 6x

0 = -7 ( a false statement).

Therefore, the solution cannot be determined.
