#n=26/5#

#3n+7-:5=17#

Divide #7# by #5# first.

#3n+7/5=17#

Multiply both sides of the equation by #5#.

#5*3n+5*7/5=17*5# =

#5*3n+cancel5*7/cancel5=17*5# =

#15n+7=85#

Subtract #7# from both sides of the equation.

#15n=85-7# =

#15n=78#

Divide both sides by #15#.

#n=78/15#

Simplify #78/15# to #26/5#.

#n=26/5#
