Question

frac{2}{5} = frac{x + 12}{x}; x = 20 frac{2}{5} = frac{x + 12}{x}; x = 4 frac{2}{5} = frac{x}{x + 12}; x = 8 frac{2}{5} = frac{x}{x + 12}; x = 4

          frac{2}{5} = frac{x + 12}{x}; x = 20
frac{2}{5} = frac{x + 12}{x}; x = 4
frac{2}{5} = frac{x}{x + 12}; x = 8
frac{2}{5} = frac{x}{x + 12}; x = 4

$frac25 = fracx + 12x; x = 20 frac25 = fracx + 12x; x = 4 frac25 = fracxx + 12; x = 8 frac25 = fracxx + 12; x = 4$
