Which expression has the same sum as the one below -15+6
15 + 6
-6 + {-15}
15 +{-6}
6 + {-15}

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14

2/3=10/15

1/5=3/15

10+3=13/15

2 13/15 is the answer
