Question

proof 1 = 2 if not I will do it in next question of mine​

Answer 1

Answer:

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.
