\frac{10}{20} + \frac{10}{x} 20 x \cdot \frac{10}{20} + 20 x \cdot \frac{10}{x} 10 x + 200 10 x - 20 x - 10 x x x = 1 = 20 x \cdot 1 = 20 x = - 200 = - 200 = \frac{- 200}{- 10} = 20 multiply ALL terms by 20 x . cancel out the denominators move the 20 x to the left side and 200 to the right simplify left side divide both sides by - 10
