7/9. 1/9 plus 2/3. You have to get the lest common denominator, so change 3 to 9 by multiplying it by three. Remember, you have to do the same thing you do to the denominator to the numerator. So, 2/3 would be 6/9. 6/9 plus 1/9 is easy, basic facts. 1 and 6 is 7, and you put the nine under. You get 7/9
<span>(-2/3)*(w-(4/9)) = -4/3 // + -4/3
(-2/3)*(w-(4/9))-(-4/3) = 0
(-2/3)*(w-4/9)+4/3 = 0
4/3-2/3*(w-4/9) = 0
(-2/3*3*(w-4/9))/3+4/3 = 0
4-2/3*3*(w-4/9) = 0
44/9-2*w = 0
(44/9-2*w)/3 = 0
(44/9-2*w)/3 = 0 // * 3
44/9-2*w = 0
44/9-2*w = 0 // - 44/9
-2*w = -44/9 // : -2
w = -44/9/(-2)
w = 22/9
w = 22/9</span>
