Since -\frac{12}{3} and \frac{2}{3} have the same denominator, add them by adding their numerators.
-\frac{10}{3}=x_{9}+5
Add -12 and 2 to get -10.
x_{9}+5=-\frac{10}{3}
Swap sides so that all variable terms are on the left hand side.
x_{9}=-\frac{10}{3}-5
Subtract 5 from both sides.
x_{9}=-\frac{10}{3}-\frac{15}{3}
Convert 5 to fraction \frac{15}{3}.
x_{9}=\frac{-10-15}{3}
Since -\frac{10}{3} and \frac{15}{3} have the same denominator, subtract them by subtracting their numerators.
x_{9}=-\frac{25}{3}
Subtract 15 from -10 to get -25.
