9600-12x-12x-15x-10000=6400
Use the distributive property to multiply 12 by 800-x.
9600-24x-15x-10000=6400
Combine -12x and -12x to get -24x.
9600-39x-10000=6400
Combine -24x and -15x to get -39x.
-400-39x=6400
Subtract 10000 from 9600 to get -400.
-39x=6400+400
Add 400 to both sides.
-39x=6800
Add 6400 and 400 to get 6800.
x=\frac{6800}{-39}
Divide both sides by -39.
x=-\frac{6800}{39}
Fraction \frac{6800}{-39} can be rewritten as -\frac{6800}{39} by extracting the negative sign.
