#n=-54/5# OR #n=1-0.8#

Combine like terms on the left side:

#color(blue)((2n)+(-7n))+5=59#

#color(blue)(2n-7n)+5=59#

#color(blue)(-5n)+5=59#

Subtract #5# from both sides:

#-5n+cancel(5color(red)(-5))=59color(red)(-5)#

#-5n=54#

Divide #-5# from both sides:

#cancel(-5)/cancel(-5)n=54/-5#

#n=-54/5# OR #n=1-0.8#
