Question

A) x-1/6=9/12
B) 2+x/4=x/3
C)5+x/8+x=3/4
D) x+2/3-x=4/1
E)x/6/5=1/12
F)6x/5=2/5/1/3
Como se faz isso?

Answer 1

Resposta:

A)

$x - \frac{1}{6} = \frac{9}{12} \\ x = \frac{9}{12} + \frac{1}{6} \\ x = \frac{54 + 12}{72} \\ x = \frac{66}{72} \\ x = \frac{11}{12}$

B)

$2 + \frac{x}{4} = \frac{x}{3} \\ \frac{8 + x}{4} = \frac{x}{3} \\ 4x = 24 + 3x \\ x = 24 \\ x = 24$
