I'll give you a hint. <u><em>You had to used pemdas stands for: p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtracting.</em></u>

First you had to calculate with parenthesis first.

$(6-4)=2-9$

Then you add and subtract from left to right.

$2-9=-7$

Final answer $\boxed{=-7}$

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.
