x = 1/2

Explanation:

`(4)/(5)x-(1)/(10)=(3)/(10)\\\\\mathrm{Add\:}(1)/(10)\mathrm{\:to\:both\:sides}\\\\(4)/(5)x-(1)/(10)+(1)/(10)=(3)/(10)+(1)/(10)\\\\(4)/(5)x=(2)/(5)\\\\\mathrm{Multiply\:both\:sides\:by\:}5\\\\5* (4)/(5)x=(2* \:5)/(5)\\\\4x=2\\\\\mathrm{Divide\:both\:sides\:by\:}4\\\\(4x)/(4)=(2)/(4)\\\\x=(1)/(2)`
