Assuming that the right statement is that if a certain number is added to both the numerator and the numerator of the fraction 7/6, the result is 3/2, find the number, the solution if found in this way:

Call x the number (certain number)

=> (7+x) / (6 +x ) = 3/2

=> (7 + x)*2 = 3*(6 + x)

=> 14 + 2x = 18 + 3x

=> 14 - 18 = 3x - 2x

=> - 4 = x

verification> ( 7 - 4) / ( 6 - 4) = 3 / 2

Answer: the number is  - 4.
