#### Answer

x = -5

#### Work Step by Step

x + $\frac{5}{4} = \frac{3}{4}x$
Subtract $\frac{3}{4}x$ from both sides:
$\frac{1}{4}x + \frac{5}{4} = 0$
Subtract $\frac{5}{4}$ from both sides:
$\frac{1}{4}x = -\frac{5}{4}$
Multiply each side by the reciprocal of the coefficient, 4:
x = ($-\frac{5}{4}$)*4 = -5
