Answer 2

Answer:

x = 3/2 or 1.5

Step-by-step explanation:

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

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

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

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

20 + x = 14 + 5x

20 - 14 = 5x - x

6 = 4x

6/4 = x

3/2 = x

Therefore, x = 3/2 or 1.5

Hope this helps you
