Question

please help me in solving this que​

Answer 1

Answer:

x=3/4

Step-by-step explanation:

(20-4x+5x-x^2)/(17-2x+7x-x^2)=1

(20+x-x^2)/(17+5x-x^2)=1

20+x-x^2=17+5x-x^2

20-17+x-5x-x^2+x^2=0

3-4x=0

3=4x

x=3/4

Answer 2

Step-by-step explanation:

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

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

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

9/9 = 1

1 = 1
