    1.2 + 6.8 + w = 12

    8 + w = 12

    w = 12 - 8 = 4

    First you add 1.2 with 6.8

    Then subtract that amount from 12.

    That would get you the answer for what W is.

    1.2+6.8+w=12

    8+w=12

    w=12-8

    w=4

    1.2+6.8+4=12

    You add 1.2 and 6.8 and get 8. subtract 8 from 12 and you get 4.

    So W=4.

    add 1.2 + 6.8 = 8

    now you have 8+w=12

    subtract 8 on both sides to get w= 4

    and thats your answer

    here is the full equation

    1.2+6.8+w = 12

    8+w=12

    w=4

    remember to add in that u subtracted 8 from both sides

    1.2+6.8+8 THUS 12-8 + w+4

  • 1 decade ago

    1.2+6.8+w=12

    Take the 1.2 over to the other side of the = so it would become a negative 6.8+ w = 12-1.2

    6.8+ w = 10.8

    Then do the same with the 6.8

    w = 10.8 - 6.8

    therefore w = 4

    if you are trying to find w you would just add 1.2 plus 6.8 and that would give you 8 then you would take 12 minus 8 and that would give you the answer for w

    just to make sure get a calculater and add 1.2 plus 6.8 plus 8 and if you get 12 then its right

    I'm confused do you have to find the value of w?

    If so, you would do 12-(1.2 +6.8) which equals 4

    If your not supposed to find the value of W then I'm not sure how you figure it out b/c the answer is already given. Well, good luck:)

    well, you add 1.2 + 6.8 and 8.0 os your equation looks like this:

    8 + w = 12

    then you subtract 8 from both sides including 12 and the 8 on the left side cancels out and on the right you now have 4. so w = 4

    hope i helped.:]
