Answer 1

Explicación paso a paso:

$\frac{5}{9} x + 2( \frac{11}{9} x - 4) = 28 \\ \frac{5}{9} x + \frac{22}{9} x - 8 = 28 \\ \frac{5}{9} x + \frac{22}{9} x - \frac{72}{9} = \frac{252}{9} \\ 5x + 22x - 72 = 252 \\ 27x = 252 + 72 \\ 27x = 324 \\ x = \frac{324}{27} = 12$

comprobamos

$\frac{5}{9} \times 12 + 2( \frac{11}{9} \times 12 - 4) = \\ \frac{60}{9 } + 2( \frac{132}{9} - \frac{36}{9} ) = \\ = \frac{60}{9} + 2( \frac{96}{9} ) = \\ \frac{60}{9} + \frac{192}{9} = \frac{252}{9} = 28$
