By arranging the equation

#7x - (2x-4) = 39#

First get rid of the paranthesis:

#7x - 2x + 4 = 39#

#x(7-2) = 39-4#

#x(5) = 35#

#x= 35/5#

#x=7#.

Your solution #x=7#

#x=7#

Distribute the negative
#7x-2x+4=39#
Combine like terms
#5x+4=39#
Subtract #4# from both side
#5x=35#
Divide both sides by 5
#x=7#
