solve the equation.
\frac{2}{3}+r = -\frac{4}{9}

Explanation:

Step1: Isolate the variable r

Subtract $\frac{2}{3}$ from both sides of the equation: $r=-\frac{4}{9}-\frac{2}{3}$.

Step2: Find a common - denominator

The common denominator of 9 and 3 is 9. Rewrite $\frac{2}{3}$ as $\frac{6}{9}$. So $r = -\frac{4}{9}-\frac{6}{9}$.

Step3: Perform the subtraction

$r=\frac{-4 - 6}{9}=-\frac{10}{9}$.

Answer:

$-\frac{10}{9}$
