$\sf{\bold{\green{\underline{\underline{Solution}}}}}$

• let Anglea's age be x and genesis age be y

Acc to the 1st statment :-

x - 4 = y

⠀⠀⠀⠀

x - y = 4 ----- ( i )

⠀⠀⠀⠀

Acc to the 2nd statement :-

4 years later :-

⠀⠀⠀⠀

angela's age = x + 4

⠀⠀⠀⠀

genesis's age = y + 4

⠀⠀⠀⠀

x + 4 = 2 ( y + 4 )

⠀⠀⠀⠀

x + 4 = 2y - 8

⠀⠀⠀⠀

2y - x = 8 - 4

⠀⠀⠀⠀

2y - x = 4 ----- ( ii )

⠀⠀⠀⠀

• adding eq i and ii

⠀⠀⠀⠀

x - y + 2y - x = 4 + 4

⠀⠀⠀⠀

y = 8

⠀⠀⠀⠀

• putting value of y in eq ( i )

⠀⠀⠀⠀

x - y = 4

⠀⠀⠀⠀

x - 8 = 4

⠀⠀⠀⠀

x = 4 + 8

⠀⠀⠀⠀

x = 12

⠀⠀⠀⠀
