multiply everything by -1 to get
-6+(-13)=?
multiply by -1
6+13=?
that's easy to figure out
6+13=19
now multiply by -1 again to put it back how it was
-6+(-13)=-19
The reason is this: you are missing 6 items. You lose 13 more items. How many are you missing now? Now you're missing 19 items.
The answer is 13. Thank you.
10 + 9 = 19 19 - 6 = 13
48
19 minus 6 equals 13.
4+2x-2x+1=13+6 Combine like terms. (4+1=5; 2x-2x=0; 13+6=19) 5=19 This problem has no solution.
13
19
2n plus 7 equals 19 2n equals 12 n equals 6
(4 + 2x) - (-2x + 1) = 13 + 6 4 + 2x + 2x -1 = 19 4x +3 = 19 4x = 19 - 3 4x = 16 therefore x = 16/4 x = 4
19
13
4 plus 6 plus 3 equals?Add 4 and 6 and get 10, then add 3 and 10 and get 13. Therefore, the answer to 4+6+3 is 13.
