This document discusses solving rational equations by multiplying each side of the equation by the common denominator to eliminate fractions. It provides 4 examples of solving rational equations: 1) 1/3 = 14/x, solved by cross multiplying to get x = 42 2) 3/(x+4) = 5/(x - 2), solved by multiplying both sides by (x+4)(x - 2) to get -13 = x 3) (x - 4)/4 + x/3 = 6, solved by multiplying both sides by 12 to get x = 12 4) 1/2 + 3/x = 3/4, solved by multiplying both sides by 4x to get x = 12.
