If the answer to a maths question is 4, John says the answer is -- 4x + 4 + 7x = 48
Mike says the answer is -- 2x + 3 = 11
Henry says the answer is 8x + 7 = 71

Then who is/are correct? Is anyone wrong? Show workout.

(x +3/2)(x+1/2) = x2 + x/2 + 3x/2 + 3/4 = x2 + 2x + 3/4 = 0 --> 4x2 + 8x + 3 ... You can plug them back into your original question to check.
