Question

1/3x-1/7=2/3 , 1/2x-1/3y=1/6 find x and y

please solve...urgent

Answer 1

Step-by-step explanation:

1/3x-1/7=2/3

1/3x=2/3+1/7

1/3x=17/21

x=17/21 ÷ 1/3

x=17/21 × 3

x=17/7................1

and, 1/2x-1/3y=1/6

putting the value of x from 1, we get

1/2 × 17/7 -1/3 y=1/6

17/14 -1/3y=1/6

1/3y =1/6-17/14

1/3y= -44/42

1/3y= -22/21

y = -22/21 ÷ 1/3

y = -22/21 × 3

y = -22/7 .

hence,. x= 17/7

y = -22/7

Answer 2

Answer:

$\frac{x}{3} = \frac{2}{3} + \frac{1}{7} \\ \\ \frac{x}{3} = \frac{17}{21} \\ \\ x = \frac{17}{7} \\ \\ = > \\ \\ \frac{1}{2} \times \frac{17}{7} - \frac{y}{3} = \frac{1}{6} \\ \\ \frac{17}{14} - \frac{1}{6} = \frac{y}{3} \\ \\ \frac{y}{3} = \frac{102 - 14}{14 \times 6} \\ \\ y = \frac{88}{28} = \frac{22}{7}$
