Answer:

x = -1

Step-by-step explanation:

\frac{2}{3} - 4x + \frac{7}{2} = -9x + \frac{5}{6}

Add 4x to each side of the equation

\frac{2}{3} - 4x + \frac{7}{2} + 4x = -9x + \frac{5}{6} + 4x

\frac{2}{3} + \frac{7}{2} = -9x + \frac{5}{6} + 4x

Subtract ⅚ from each side

\frac{2}{3} + \frac{7}{2} - \frac{5}{6} = -9x + \frac{5}{6} + 4x - \frac{5}{6}

\frac{2}{3} + \frac{7}{2} - \frac{5}{6} = -9x + 4x

\frac{4 + 21 + 5}{6} = -5x

\frac{30}{6} = -5x

5 = -5x

Divide both sides by -5

\frac{5}{-5} = \frac{-5x}{-5}

-1 = x

x = -1
