We have a fraction with the unknown in the denominator, review how to treat unknowns in the denominator as a refresher for this exercise: <span>(2/3) - (1/x + 6) = 2 </span>(2/3) - (1 + 6x)/x = <span>2 </span>(2/3) - 2 = (1 + 6x)/x 2/3 - 6/3 = (1 + <span>6x)/x -4/3 = </span>(1 + <span>6x)/x -4x = 3</span>(1 + <span>6x) </span><span>-4x = 3 + 18x </span>22x = -3 x = -3/22
