Answer:
1. n<-10
2. p ≥ -6
3. k > 3
4. d ≥ 18
5. c ≤ 5
6. b ≥ -4
Step-by-step explanation:
1. subtract 7 from both sides to leave n by itself
n + 7 -7< -3 -7
n < -10
2. divide by 5 on both sides to get p by itself
5p/5 ≥ -30/5
p ≥ -6
3. subtract 11 from both sides to get k by itself
14 -11 < k + 11 - 11
3 < k
which is also equal to
k > 3
4. multiply by -3 on both sides to get d by itself
(d/-3)(-3) ≤ -6 *-3
because -3 is negative, the signs flip
d ≥ 18
5. add 2.5 both sides to leave c on its own
c -2.5 +2.5 ≤ 2.5 + 2.5
c ≤ 5
6. divide by -3 on both sides to get b by itself
12/-3 ≥ -3b/-3
because -3 is negative you flip the sign
-4 ≤ b
which is also equal to
b ≥ -4
