# x = -23/4#

# 2x - 8 = 6x + 15#

# -15 - 8 = 6x - 2x#

# -23 = 4x#

# x = -23/4#

#x=-23/4#

Given -

#2x-8=6x+15#

Add #-6x# to both sides

#2x-6x-8=6x-6x+15#

#-4x-8=cancel(6x)cancel(-6x)+15#

#-4x-8=15#

Add #+8# to bothsides

#-4x-8+8=15+8#

#-4xcancel(-8)cancel(+8)=23#

#-4x=23#

Divide both sides by #-4#

#(-4x)/(-4)=23/(-4)#

#(cancel(-4)x)/cancel(-4)=23/(-4)#

#x=-23/4#
