Question 514830: Solve the inequality and represent your answer in set builder notation. Show all work.
7-10z+4>-11z+5
and this is what I got.. Is it right?
7 - 10z + 4 > -11z + 5
11 - 10z > -11z + 5
11z - 10z > 5 - 11
z > -6

{z ∈ R | z > -6}

Suppose 7 is NOT part of the inequality, we have:
10z + 4 > -11z + 5
11z + 10z > 5 - 4
21z > 1
z > 1/21

{Z ∈ R | z > 1/21}
