Answer:

x = 7

Explanation:


10[2x-4]=100\\\\\mathrm{Divide\:both\:sides\:by\:}10\\(10\left(2x-4\right))/(10)=(100)/(10)\\\\Simplify\\2x -4=10\\\\\mathrm{Add\:}4\mathrm{\:to\:both\:sides}\\2x-4+4=10+4\\\\Simplify\\2x =14\\\\\mathrm{Divide\:both\:sides\:by\:}2\\(2x)/(2)=(14)/(2)\\\\Simplify\\x = 7
