Answer 1

Answer:

The answer is -1/4

Step-by-step explanation:

$x = (3x + \frac{1}{4} x ) \\ 4 \times 2 = 3x + 1 \\ 4 \times 2 - 3 x - 1 = 0 \\ 4 \times 2 - 4x + x - 1 = 0 \\ 4x(x - 1) + 1(x - 1) = 0 \\ (x - 1)(4x + 1) = 0 \\ since \: (x - 1) = 0 \: or \: (4x + 1) = 0 \\ then \: x = 1 \: or \: x \: = \frac{ - 1}{4}$
