#### Explanation:

#"to eliminate the fraction, multiply ALL terms by 5"#

#rArr(-10xx5)+cancel(5)xx-n/cancel(5)=(7xx5)#

#rArr-50-n=35#

#"add 50 to both sides"#

#cancel(-50)cancel(+50)-n=35+50#

#rArr-n=85#

#"multiply both sides by - 1"#

#rArrn=-85#

#color(blue)"As a check"# Substitute this value into the left side of the equation and if equal to the right side then it is the solution

#"left side "=-10-((-85))/5=-10+17=7=#

#rArrn=-85" is the solution"#
