Question

Can someone please help with this its gyometry

Answer 1

Check the picture below.

`\cfrac{x}{56}=\cfrac{18+x}{21+56}\implies \cfrac{x}{56}=\cfrac{18+x}{77}\implies 77x=1008+56x \\\\\\ 21x=1008\implies x=\cfrac{1008}{21}\implies x=48`

Answer 2

X=48

Explanation:

X/18

56/21

21 times x is 21x

18 times 56 is 1008

1008 divided by 21 is 48
