Explanation:
First expand out the brackets:
and
Hence, the equation becomes:
Now rearrange to make
-
Subtract
#5x# from both sides to obtain:
#=> 14x-5x-7=5x-5x-70#
#=> 9x-7=70# -
Then add 7 to both sides to isolate
#x#
#=> 9x-7+7=-70+7#
#=> 9x = -63# -
Finally, divide both sides by 9 to obtain
#x#
#=> x=-63/9#
Hence,
