-7/3x+2/3=-11

If your problem is this:

(-7/3)x + 2/3 = -11

Multiply everything by 3 to get rid of the denominator:

3[(-7/3)x + 2/3 = -11]

-7x + 2 = -33

Subtract 2 from both sides (whatever operation you do to one side of an equation you must do to the other side as well):

-7x + 2 - 2 = -33 - 2

-7x = -35

Now divide both sides by -7 to get x by itself:

-7x/-7 = -35/-7

x = 5

Substitute 5 for x in the original equation to check this answer. It always helps to check your work!
