Pls help on both questions

Step-by-step explanation:

Both expression are the same :

14 = 2(x + 3)

By expansion :

14 = 2*x + 2*3

14 = 2x + 6

Hence ;

Both expression are the same

Weight of one circle :

Final weight on both sides are equal:

Weight on Left hand side = 14

Weight on right hand side = 3*x + 3*x

Weight on Left hand side = Weight on right hand side

14 = 3x + 3x

14 = 6x

x = 14 / 6

x = 2.333
