Question

(2+x) (7-x) / (5-x) (4+x) =1​

Answer 1

Answer:

x = 3/2

Step-by-step explanation:

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

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

14 - 2x + 7x - x² = 20 + 5x - 4x - x²

14 + 5x = 20 + x

5x - x = 20 - 14

4x = 6

x = 6 /4

x = 3/2

Answer 2

Answer:

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

14 - 2x + 7x - x² = 20 + 5x -4x - x²

14 + 5x = 20 + x

5x - x = 20 - 14

4x = 6

x = 3/2
