Question

B + 7 + 12 = 13 ? Please tell me how you did it! Thanks.

Answer 1

It is -6.

Explanation:

7 + 12 is 19

b + (7 + 12) = 13

b + (19) = 13

-6 + 19 = 13

Answer 2

The answer you are looking for is b = -6.

There are 2 ways to find this. You could use...

1. Add together 7 and 12 to get 19, then subtract 19 from both sides to get b = -6. OR...
2. Subtract 12 from both sides to get b + 7 = 1, then subtract 7 from both sides to get b = -6.

Either way, you will get the same answer of b = -6. One method is just longer than the other. I hope this helps!
