#### Explanation:

#"collect terms in x on the left side of the equation and"#

#"numeric values on the right side"#

#"add 5x to both sides"#

#-15x+5x=-30cancel(-5x)cancel(+5x)#

#rArr-10x=-30#

#"divide both sides by "-10#

#(cancel(-10) x)/cancel(-10)=(-30)/(-10)#

#rArrx=3#

#color(blue)"As a check"# Substitute this value into the equation and if both sides are equal then it is the solution.

#"left "=-15xx3=-45#

#"right "=-30-(5xx3)=-30-15=-45#

#rArrx=3" is the solution"#
