#color(blue)(x =15#

#4-2(x-7)=-12#

#4-2*x + (-2) *(-7)=-12#

#4-2x + 14=-12#

#-2x + 14+4=-12#

#-2x + 18=-12#

#-2x =-12-18#

#-2x =-30#

#x =(-30)/(-2)#

#color(blue)(x =15#

#x=15#

We can distribute the #-2# on the left side to get

#4-2x+14=-12#

Next, we can simplify the left side constants to get

#-2x+18=-12#

Next, subtract #18# from both sides to get

#-2x=-30#

Lastly, we can divide both sides by #-2# to get

#x=15#

Hope this helps!
