~~~~|2x +0.75| = 5 \frac 67\\\\\\\implies \left|2x+\frac 34\right| = \frac{41}7\\\\\\\implies 2x +\frac 34 = \frac{41}7~~~~ \text{or}~~~~ 2x + \frac 34 =- \frac{41}7\\\\\\\implies 2x = \frac{41}7- \frac 34~~~~ \text{or}~~~~ 2x = -\frac 34 - \frac{41}7\\\\\\\implies 2x = (143)/(28)~~~~~~~~ \text{or}~~~~ 2x = -(185)/(28)\\\\\\\implies x = (143)/(56)~~~~~~~~~ \text{or}~~~~~ x = -(185)/(56)\\\\\\


\implies x = 2(31)/(56)~~~~~~~~~ \text{or}~~~~~ x = -3(17)/(56)\\
