Question

3/4 . 2x=4/3 . 1-x qual o valor de x

Answer 1

$\frac{3}{4}\cdot \:2x=\frac{4}{3}\cdot \:1-x\\\\\frac{3}{4}\cdot \:2x=\frac{4}{3}-x\\\\\frac{3}{4}\cdot \:2x+x=\frac{4}{3}-x+x\\\\\frac{5}{2}x=\frac{4}{3}\\\\2\cdot \frac{5}{2}x=\frac{4\cdot \:2}{3}\\\\5x=\frac{8}{3}\\\\\frac{5x}{5}=\frac{\frac{8}{3}}{5}\\\\x=\frac{8}{15}$
