Answer:
[tex]-\frac{6}{7}[/tex]
Step-by-step explanation:
[tex]-\frac{9}{14} + -\frac{3}{14}[/tex]
You can change the + - into a -,
you are basically figuring out: -9 - 3
which is -12!
Put that number as the numerator and 14 as a denominator
You get - 12 / 14, but you can still simplify it!
divide both of the numbers by 2...
So you end up getting: [tex]-\frac{6}{7}[/tex]
