Homework Help: math

Im a little confused can someone please help?
Solve: -7x-24=-26 1/3

This is what i did, not sure if I did it right.
-7x-24=-26 and 1/3, -24 from both sides
-7x= 2 and 1/3, then divide by -7 and got x= -2 and 1/3 over -7 I have no idea how to right that so I know it has to be wrong, please help!!

x=-46/21

Double check the math on this.
-7*-(46/21)-24 = 26/3

-7*-1/3 - 24 = 26+1/3
x=1/3

first get rid of that useless mixed fraction.
-7x-24=-79/3
now multiply each term by -3 to get rid of fractions and all those negative signs
21x + 72 = 79
21x = 7
x = 7/21 = 1/3
