4/x + 3x = 3(x+12)
Choose the correct choice from the following options
A) -9 B) -1/3 C) -1/9 D) 1/9 E) 9
We can solve - expand the right side, multiply by x on both sides and then subtract away the 3x^2 terms:   (4/X) + 3x = 3(x+12)   (4/x) + 3x = 3x + 36   4 + 3x^2 = 3x^2 + 36x   4 = 36x   1/9 = x   and to confirm, you can plug that answer back into the original equation to see that it makes the left and right sides equal.   1/9
