C + (-c) = 0 Opposite number or additive inverse of a number a is the number that, when added to a, yields zero
<span>1) There are no solutions for this equation in the solution set.
2) The solution set is {5} because 15/5 = 3
3) The solution set is {8} because
4) The solution set is {20} because 20 - 13 = 7
5) The solution set is {66} because 22 x 3 = 66
6)

<span>
11) The solution set is {6, 7} because:
6 -2 < 6, which is 4 < 6
AND
7 - 2 < 6, which is 5 < 6
12) </span><span>The solution set is {9, 11} because:
</span>
3 ≥ 25/9, which is 3 ≥ <span>2.77777777778
</span>AND
3 ≥ 25/11, which is 3 ≥ 2.2727272727
Hope this helps :D
