Answer:
(x + 3) : (x + 11) = (x - 2) : (x + 1)
∴ (x + 3)(x +1) = (x – 2)(x + 11)
∴ x(x +1) + 3(x + 1) = x(x + 11) – 2(x + 11)
∴ x2 + x + 3x + 3 = x + x – 2x – 22
∴ x2 + 4x + 3 = x2 + 9x – 22
∴ 4x + 3 = 9x – 22
∴ 3 + 22 = 9x – 4x
∴ 25 = 5x
∴ x = 5

ANSWER:
To Solve:
- (x + 1) × (x + 2) = (x + 11) × (x - 2)
Solution:
We are given that,
Opening brackets,
Cancelling x^2,
Transposing 3x to RHS, and 22 to LHS,
Transposing 6 to RHS,
Hence, value of x = 4.
Verification:
We are given that,
Substituting value of x as 4,
As LHS = RHS,
HENCE VERIFIED!!
