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.
