Question

Resolva

A)3x-2/4=2+x/5
B)x-3/5=2x-1/5
C)3x-1/4=x+2/3
D)5-x/3=2+x/2

Answer 1

A)

$30x -5 = 20 + 2x \\ 28x = 25 \\ x = \frac{25}{28}$

B)

$2x - x = - \frac{3}{5} + \frac{1}{5} \\ x = - \frac{2}{5}$

$2x = \frac{2}{3 } + \frac{1}{4} \\ x = \frac{11}{24}$

D)

$\frac{x}{2} + \frac{x}{3} = 3 \\ 5x = 18 \\ x = \frac{18}{5}$
