Answer

x = -2

Work Step by Step

$\frac{7}{8}x + \frac{1}{4} = \frac{3}{4}x$ Subtract $\frac{3}{4}x$ from both sides: $\frac{7}{8}x - \frac{3}{4}x + \frac{1}{4}$ = 0 $\frac{1}{8}x + \frac{1}{4}$ = 0 Subtract $\frac{1}{4}$ from both sides: $\frac{1}{8}x = -\frac{1}{4}$ Multiply each side by the reciprocal of the coefficient, 8: x = ($-\frac{1}{4}$)8 x = -2
