Question

The solution of a+b>12 is a>−3. What is the value of b?

Answer 1

we conclude that when we substitute b = 15, the solution of the inequality becomes:

`a>-3`

Therefore, the value of b = 15.

Explanation:

Given the inequality expression

`a+b>12`

Putting b = 15 in the inequality expression

`a+b>12`

`a+15>\:12`

subtract 15 from both sides

`a+15-15>12-15`

simplify

`a>-3`

Thus, we conclude that when we substitute b = 15, the solution of the inequality becomes:

`a>-3`

Therefore, the value of b = 15.
