Which value of x satisfies the inequality below? 1 3/7 < x

A: x= 1 1/4
B: x=1 2/7
c: x= 1 1/2
d: x= 1 1/3​

1. x = 10

2. B.  3/7

Step-by-step explanation:

1. (x - 2)/ 4 - (3x + 5)/7 = - 3

 7(x -2) -4(3x +5) = -84 . . . . . . . multiply by 28

 7x -14 -12x -20 = -84 . . . . . . . . eliminate parentheses

 -5x -34 = -84 . . . . . . . . . . . . . . collect terms

 -5x = -50 . . . . . . . . add 34

 x = 10 . . . . . . . . . . . divide by -5

2. 1/(1 + 1/(1 - 1/x)) = 4

 1 = 4(1 +1/(1 -1/x)) . . . . multiply by the denominator

 -3 = 4/(1 -1/x) . . . . . . . eliminate outer parentheses, subtract 4

 -3(1 -1/x) = 4 . . . . . . . multiply by the denominator

 -3 +3/x = 4 . . . . . . . . eliminate parentheses

 3/x = 7 . . . . . . . . . . . add 3

 x = 3/7 . . . . . . . . . . . multiply by x/7

1. minimum

2. 6400

3. eight

hope this !
