#### Explanation:

#"Add 2 to both sides of the equation"#

#-5xcancel(-2)cancel(+2)=-107+2#

#rArr-5x=-105#

#"divide both sides by "-5#

#(cancel(-5) x)/cancel(-5)=(-105)/(-5)#

#rArrx=21#

#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 "=(-5xx21)-2=-105-2=-107=" right"#

#rArrx=21" is the solution"#
