Answer: [tex]x=-\frac{2}{3}[/tex]

Step-by-step explanation:

Given the following equation:

[tex]\frac{2}{3}-4x+\frac{7}{2}=-9x+\frac{5}{6}[/tex]

We need to solve for "x":

1. Move the fractions to one side of the equation and the x-terms to the other side:

[tex]-4x+9x=\frac{5}{6}-\frac{2}{3}-\frac{7}{2}[/tex]

2. Add the like terms.

To add the fractions we must find the Least Common Denominator (LCD):

[tex]6=2*3\\3=3\\2=2\\\\LCD=2*3=6[/tex]

Then:

[tex]5x=\frac{5-4-21}{6}\\\\5x=-\frac{20}{6}\\\\5x=-\frac{10}{3}[/tex]

3. Finally, divide both sides of the equation by 5:

[tex]\frac{5x}{5}=\frac{-\frac{10}{3}}{5}\\\\x=-\frac{2}{3}[/tex]

By isolating the variable, we will see that the solution is x = -2/3.

How to solve the equation?

Here we have the equation:

2/3 - 4x + 7/2 = -9x + 5/6

And we want to solve this for x. To do this, we need to move all the terms with x to the left side and all the terms without x to the right side, we will get:

-4x + 9x = 5/6 - 2/3 - 7/2

Now we simplify both sides:

(-4 + 9)*x = 5/6 - 4/6 - 21/6

5x = -20/6

Now we divide both sides by 5:

x = (-20/6)*(1/5) = -4/6

x = -4/6 = -2/3

So the solution of the equation is x = -2/3.
