Question

What do you think? Find values for A and B that make each mathematical sentence true.+A+B=-1 A=? B=?-A + +B=0 A=?B=?-A- -B=-2 A= ?B= ?

Answer 1

For the first equation, +A + - B = -1, there are many possible values of A and B. It can be the following:

1. If A = 1, then B = 2

2. If A = 2, then B = 3.

3. If A = 3, then B = 4.

For the second equation, -A + +B = 0, there are still many possible values of A and B. It can be the following:

1. If A = 1, B = 1.

2. If A = 2, B = 2.

3. If A = 3, B = 3.

Lastly, for the third equation, -A - -B = -2, there are still many possible values of A and B. It can be the following:

1. If A = 1, then B = -1.

2. If A = 2, then B = 0.

2. If A = 3, then B = 1.
