#x= -11#

#5−3x=4x+82#

#-3x-4x=82-5#

#(-7x)/(-7)=77/ (-7)#

#x= -11#

combine like terms and solve for x

#x =-11#

# 5-3x = 4x + 82#

#5 -3x -4x = 4x -4x + 82" "# This gives

# 5 - 7x = 82" "# subtract 5 from both sides

# 5 -5 - 7x = 82 -5 " "# This gives

# -7x = 77" " # divide both sides by #-7 #

# (-7x)/-7 = 77/-7# so

#x = - 11#
