Enter your answer and show all the steps that you use to solve this problem in the space provided. a. solve a–9=20 b. solve b–9> 20 c. how is solving the equation in part a similar to solving the inequality in part b? d. how are the solutions different?

A) The value of a is 29.

B) The value of b is greater than 29.

C) In both part A and part B we have used a common property  which is addition property and that we have add 9 on both side of equation in both parts.

D) The value of a in part A is equal to 29 whereas in part B the value of b is greater than 29.

Step-by-step explanation:

Solving for Part A.

Given,

We have to solve for a.

By using addition property of equality, we will add both side by 9;

Hence the value of a is 29.

Solving for Part B.

Given,

We have to solve for b.

By using addition property of inequality, we will add both side by 9;

Hence the value of b is greater than 29.

Solving for Part C.

In both part A and part B we have used a common property  which is addition property and that we have add 9 on both side of equation in both parts.

Solving for Part D.

The value of a in part A is equal to 29 whereas in part B the value of b is greater than 29.
