Question

solve the following equation also verify the solution (a)5-x by 5+x =2 by 5​

Answer 1

Step-by-step explanation:

( 5 - x ) / (5 + x ) = 2/5

cross multiplication

5 * ( 5 - x ) =( 5 + x ) * 2

25 - 5x = 10 + 2x

15 = 7x

x = 15/7

Vérification :

LHS =

( 5 - 15/7)/(5 + 15/7 ) = (35-15)/(35+15)

= 20 / 50 = 2/5 = RHS
