Question

:(2 + 2b - a - ab) = (1 +b) =​

Answer 1

Answer:

a(1+b) = 1

Step-by-step explanation:

given that (2 + 2b - a - ab) = (1 +b)

2+2b-a-ab = 1+b

2 - 1 +2b - b - a - ab =0

1 + b - a - b - ab =0

1 - a - ab =0

a(1+b) = 1

Answer 2

Answer:

a = 1

b = -1

Step-by-step explanation:

(2 + 2b - a - ab) = (1 + b)

=> -a - ab = -b - 1

=> a(-1 - b) = -b - 1

=> 1

$\frac{a(−1−b)}{−1−b} = \frac{ -b}{−1−b}$

$\frac{a(−1−b)}{−1−b} = \frac{ -b}{−1−b} \frac{ -1}{−1−b}$

After solving

a = 1

Putting the value of a in the main equation we get

b = -1
