3/2

Step-by-step explanation:

explained as above

Answer 2

Answer:

x=3/2

Step-by-step explanation:

Given that-

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

By cross multiplicatio-

(4 + x)(5 - x)=(2 + x)(7 - x)

20 - 4 x + 5 x - x²=14 - 2 x + 7 x - x²

20 + x = 14 + 5 x

20 - 14 = 5 x - x

4 x = 6

x = 6/4

x=3/2

Hence , the value of x is 3/2
