If 6 - 12/X = 7 - 7/X, then X =
Choices: A) -5 B) 19 C) -7/5 D) 1 E) 5/6
We're given the equation 6 - 12/X = 7 - 7/X. We're asked for the value of X.   The common-denominator of these 4 numbers is X, so we need to multiply both sides of the equation by X, giving us...   6X - 12X/X = 7X - 7X/X   We can then eliminate that denominator, which gives us....   6X - 12 = 7X - 7   -5 = X   -5
