Question

1/3+2/5x=3 cual es la respuesta

Answer 1

Respuesta:

1/3+2/5x=3

$\frac{1}{3}+\frac{2}{5}x=3\\\\\\\frac{1}{3}+\frac{2}{5}x-\frac{1}{3}=3-\frac{1}{3}\\\\\\\frac{2}{5}x=\frac{8}{3}\\\\\\5\cdot \frac{2}{5}x=\frac{8\cdot \:5}{3}\\\\\\2x=\frac{40}{3}\\\\\\\frac{2x}{2}=\frac{\frac{40}{3}}{2}\\\\\\x=\frac{20}{3}$
