Question

2x/3+3x/5=9/15+40$2x/3+3x/5=9/15+40$

Answer 1

Respuesta:

$\frac{2x}{3}+\frac{3x}{5}=\frac{9}{15}+40\\\\\frac{2x}{3}+\frac{3x}{5}=\frac{3}{5}+40\\\\\frac{2x}{3}+\frac{3x}{5}=\frac{40\cdot \:5}{5}+\frac{3}{5}\\\\\frac{2x}{3}+\frac{3x}{5}=\frac{40\cdot \:5+3}{5}\\\\\frac{2x}{3}+\frac{3x}{5}=\frac{203}{5}\\\\\mathrm{Multiplicar\:por\:el\:minimo\:comun\:multiplo=}15\\\\\frac{2x}{3}\cdot \:15+\frac{3x}{5}\cdot \:15=\frac{203}{5}\cdot \:15\\\\\mathrm{Simplificar}10x+9x=609\\\\19x=609\\\\\frac{19x}{19}=\frac{609}{19}\\\\x=\frac{609}{19}$
