Explanation:
First expand out the brackets:
and
Hence, the equation becomes:
Now rearrange to make

Subtract
#5x# from both sides to obtain:
#=> 14x5x7=5x5x70#
#=> 9x7=70# 
Then add 7 to both sides to isolate
#x#
#=> 9x7+7=70+7#
#=> 9x = 63# 
Finally, divide both sides by 9 to obtain
#x#
#=> x=63/9#
Hence,
