#x = 11#

#7x - 5 = 6x + 6#

To find the variable #x#, we have to make it by itself.

To do so, first add #color(blue)5# to both sides of the equation:
#7x - 5 quadcolor(blue)(+quad5) = 6x + 6 quadcolor(blue)(+quad5)#

#7x = 6x + 11#

Now subtract #color(blue)(6x)# from both sides of the equation:
#7x quadcolor(blue)(-quad6x) = 6x + 11 quadcolor(blue)(-quad6x)#

Therefore,
#x = 11#

Hope this helps!
