3(0,75x+5/6)-2x=1/4x+2,5

Answer 1

$3(0.75x + \frac{5}{6} ) - 2x = \frac{1}{4x} +2.5 \\ \\ 2.25x + \frac{23}{6} - 2x = \frac{1}{4x} + 2.5 \\ \\ 2.25x - 2x - \frac{1}{4x} = 2.5 - \frac{23}{6} \\ \\ 0.25x - \frac{1}{4x} = 0 \\ \\ {x}^{2} - 1 = 0 \\ {x}^{2} = 1 \\ \\ x = 1 \: \: \: \: \: \: \: \: \: \: \: \: \: x = - 1$
