Question

Decide what values of the variable cannot be solutions for each equation.

Answer 1

Step-by-step explanation:

$\frac{1}{4x} - \frac{2}{x} = 3 \\ \frac{1}{4x} - \frac{2}{x} \times \frac{4}{4} = 3 \\ \frac{1}{4x} - \frac{8}{4x} = 3 \\ \frac{1 - 8}{4x} = 3 \\ \frac{ - 7}{4x} = 3 \\ 4x = \frac{ - 7}{3} \\ x = \frac{ - 7}{12} \\ thank \: you$

Answer 2

Answer:

$→ \frac{1}{4x} - \frac{2}{x} = 3 \\ \frac{1}{4x} - \frac{(2 \times 4)}{(x \times 4)} = 3 \\ \frac{1}{4x} - \frac{8}{4x} = 3 \\ \frac{(1 - 8)}{4x} = 3 \\ \frac{( - 7)}{4x} = 3 \\ \frac{1}{x}= \frac{(3 \times 4)}{( - 7)} \\ \frac{1}{x}= \frac{12}{( - 7)} \\ \boxed{x = \frac{( - 7)}{12} }$

• x = -7/12 is the right answer.
