If the solution of a + b > -4 is a > -9, then the value of b is 5
How to determine the value of b
From the question, we have the following parameters that can be used in our computation:
a + b > -4
Also, we have
a > -9
From the expression a + b > -4, we have
a > -4 - b
if a > -4 - b and a > -9, then
-4 - b = -9
Multiply through by -1
4 + b = 9
So, we have
b = 9 - 4
Evaluate
b = 5
Hence, the value of b is 5
