Question

solve for x. 2/5 (x - 1/2) = -2 3/4

Answer 1

Answer: x = -51/4 or -12 3/4

Step-by-step explanation:

$\begin{array}{l}\frac{2}{5}\left(\frac{x-1}{2}\right)=-2\frac{3}{4}\\\\\frac{2}{5}\left(\frac{x-1}{2}\right)=-\frac{11}{4}\\\\5\cdot\frac{2}{5}\cdot\frac{x-1}{2}=5\left(-\frac{11}{4}\right)\\\\x-1=-\frac{55}{4}\\\\x-1+1=-\frac{55}{4}+1\\\\x=-\frac{51}{4}\ or\ -12\ \frac{3}{4}\end{array}$

Answer 2

x= -51/8 or and alternative form is x= -6 3/4
