Question

If x-1/2x = 3, find x+1/2x.​

Answer 1

Answer:

$\frac{x - 1}{2x} = 3 \\ x - 1 = 3 \times 2x \\ x - 1 = 6x \\ - 1 = 6x - x \\ - 1 = 5x \\ 5x = - 1 \\ x = \frac{ - 1}{5} \\ now \: \frac{x + 1}{2x} \\ \frac{ \frac{ - 1}{ \cancel5} + 1 }{ 2 \times \frac{ - 1}{ \cancel5} } \\ = \frac{ - 1 + 1}{ - 2} \\ = \frac{0}{ - 2} = 0$
