Answer:

x=-\frac{11}{18}

Step-by-step explanation:

-1\frac{7}{9}=(-2\frac{5}{6} + \frac{1}{3})x

Solve parenthesis first

-2\frac{5}{6}  + 1/3

Find a common denominator.

The common denominator would be 6.

Because the first expression already has a denominator of 6 it stays the same.

\frac{1}{3} = \frac{2}{6}

-2\frac{5}{6} + \frac{2}{6} = -2\frac{7}{6} = -1\frac{1}{6}

Put that into the original equation.

-1\frac{7}{9}=(-1\frac{1}{6} )x

Isolate the x. Add 1\frac{1}{6} to each side.

-1\frac{7}{9}+ 1\frac{1}{6}=x

Find a common denominator.

we can use 18 as the common denominator.

-1\frac{7}{9}+ 1\frac{1}{6}= -1 \frac{14}{18} +1\frac{3}{18}= x

Add.

-\frac{11}{18} =x

We cannot simplify so our answer stays the same.

X=180-170

X=10
