\left ( -\:\frac{11}{2}\:x\:+\:3\right )\:-\:2\left ( -\:\frac{11}{4}\:x\:-\:\frac{5}{2}\right ) =

Answer 1

- \frac{11}{2}x + 3 - 2\left( -\frac{11}{4}x - \frac{5}{2}\right) = - \frac{11}{2}x + 3 - 2\times -\frac{11}{4}x - 2\times -\frac{5}{2} = - \frac{11}{2}x + 3 + \frac{11}{2}x + 5 = \frac{11}{2}x + \frac{11}{2}x + 3 + 5 = \frac{11}{2}x + \frac{11}{2}x + 8 = 11x + 11x + 8 = 22x + 8
