Question

(5x sobre 2)(3 sobre 8) igual a x mas 6​

Answer 1

Explicación paso a paso:

$( \frac{5x}{2} )( \frac{3}{8}) = x + 6 \\ \\ \frac{15}{16} x = x + 6 \\ \\ 16( \frac{15}{16} x) = 16(x + 6) \\ \\ 15x = 16x + 96 \\ 15x - 16x = 96 \\ - 1x = 96 \\ x = - 96 \\ comprobación \\ (\frac{5 \times - 96}{2} )( \frac{3}{8} ) = - 96 + 6 \\ \\ (- \frac{480}{2} )( \frac{3}{8} ) = - 90 \\ \\ - \frac{1440}{16} = - 90 \\ \\ - 90 = - 90$
