Answer:
v > 4 is simplified expression.
Step-by-step explanation:
Given that:
v + 5 > 9
This expression says that when 5 is added to a variable v it will be greater than 9 So we will simplify it to get the value for variable v:
Subtracting 5 from both sides:
v + 5 - 5 > 9 - 5
v > 4
This is the simplified expression for given question.
