$-\frac{5}{2}x+\frac{3}{4}x=-\frac{3}{4}\\\\-\frac{5\times2}{2\times2}x + \frac{3}{4}x=-\frac{3}{4}\\\\\frac{-10}{4}x+\frac{3}{4}x=-\frac{3}{4}\\\\\frac{-10+3}{4}x=-\frac{3}{4}\\\\-\frac{7}{4}x=-\frac{3}{4}\\\\-\frac{7}{4}x \times -4 =-\frac{3}{4} \times -4\\\\7x = 3\\\\\boxed{\bf{x =\frac{3}{7}}}$
