Question

Someone help with math:

For which equation is b = 5 not the solution?

options:

1. 8 - b = 13
2. b + 6 = 11
3. b + 4 = 9
4. 12 - b = 7

Answer 1

1. 8 - b = 13

Explanation:

It says for which equation is b = 5 not the solution.

So, we need to plug in 5 into every b, and find out which one is incorrect.

1. 8 - 5 = 13 (incorrect)

2. 5 + 6 (correct)

3. 5 + 4 = 9 (correct)

4. 12 - 5 = 7 (correct)

Therefore, option 1 is the answer to your question.

Answer 2

option 2 and 3

b+6=11

b+4=9
