#x=-4#

Begin by distributing the #-5# to both #7x# and #-7#

#159=color(red)(-5)*7xcolor(red)(-5)*-7+4x#

#159=-35x+35+4x#

Move like terms to one side by subtracting #35# from both sides:

#159color(red)(-35)=-35x+35color(red)(-35)+4x#

#124=-35x+4x#

Simplify the right side by adding like terms:

#124=-31x#

Divide #-31# from both sides to solve for #x#

#159/-31=cancel(-31)/cancel(-31)x#

#-4=x#
