Answer 1

Answer:

the question is wrong

Step-by-step explanation:

2 cannot be 1

Answer 2

Answer:

let a = b

multiply by a on both sides,

a² = ab

subtract b² on both sides

a² - b² = ab- b²

(a + b)(a - b) = b(a - b)

(a + b)(a - b) / (a - b) = b

a + b = b

because a = b,

2b = b

2 = 1

Hence, proved
