#x=16/5#

show below

#x/2=(x+8)/7#

#7x=2*(x+8)#

#7x=2x+16#

#7x-2x=16#

#5x=16#

#x=16/5#

#16/5#

Here

#x/2= (x+8)/7#

Cross-multiplying, we get

#7x=2(x+8)#

#7x=2x+16#

#7x-2x=16#

#5x=16#

Hence

#x=16/5#

#x=16/5#

Use the cross multiply, kiss and smiles, or however you like to call it method where you multiply opposites, so the divide is removed.

#rArr 7(x)=2(x+8)#

#rArr 7x=2x+16#

#rArr 5x=16#

#rArr x=16/5#
