Answer:

Step-by-step explanation:

2-x/x-7=3/5

By doing cross multiplication we get,

10-5x=3x-21

10+21=3x+5x

31=8x

x=31/8

2 - x / x - 7 = 3/5

By cross multiplication

(2 - x)5 = 3(x - 7)

10 - 5x = 3x -21

-5x -3x = -21 - 10

-8x = -31

x = -31/-8

x = 31/8

Verification :

(2 - 31/8)/(31/8 - 7) = 3/5

(2(8)/8 - 31/8)/(31/8 -7(8)/8) = 3/5

(16/8 - 31/8)/(31/8 - 56/8) = 3/5

(-15/8)/(-25/8) = 3/5

-15/8 * -8/25 = 3/5

120/200 = 3/5

12/20 = 3/5

3/5 = 3/5

RHS = LHS

Hence verified.
