Question

1+1 is equal to what I don't know?​

Answer 1

Answer:

2

Step-by-step explanation:Since a = b (that's the assumption we started with), we can substitute b in for a to get: b + b = b. Combining the two terms on the left gives us: 2b = b. Since b appears on both sides, we can divide through by b to get: 2 = 1.
